Hello,
Curiosity got the best of me so I sent the flag to Dave Martucci for a professional assessment. I was extremely pleased with the results. I first found Dave's name on this forum and I highly recommend to anyone with questions about a flag to consider his services.
His findings confirmed what others had previously posted about the flag's age. It is not an original time-period 30 Star flag. It was a great education though and I learned much from the comments here and my conversations with Dave Martucci. I'm posting his conclusions below after he he personally examined the flag.
The item is specifically described as follows: A 30-star US Flag measuring approximately 34 inches by 59 inches, not counting the approximate 1¼ inch header, consisting of 13 alternate red and white stripes and a blue canton measuring approximately 24½ inches by 18¾ inches that has 7 stripes next to it and bearing 30 white stars in staggered rows of 7-8-7-8 from the top. There are 6 stripes below the canton. The stripes measure approximately 2⅔ inches each in width. The stars are set such that there is a larger amount of blue above them than below them and they all “point” in different directions, a pattern you refer to as “dancing”, and each one measures approximately 2⅓ inches in diameter.
The body of the flag is made from wool bunting which I believe to be first grade English bunting. The material is woven such that the yarns used are of two weights, a lighter weight that comprises most of the warp and weft and a slightly heavier yarn that is woven in approximately every 8-12 rows in each direction. This is a hallmark of fine English bunting. All of the sewing on the body appears to be by machine and the sewing thread appears to be machine spun, probably mercerized cotton.
The stars are made of cotton sheeting and they are machine appliquéd onto each side using a straight stitch in a “pentagram” pattern going from point to point and crossing the other rows of stitching at the center of each star. On what we would call the obverse side you can see that several of the stars have pinholes where they were pinned onto the flag before sewing. There are no such holes on the reverse. This indicates the individual cut out stars were pinned to the front, then a sheet of material was layered below the blue field and then the stars were stitched on and the stars on the back were cut away. The header is hand-sewn on and is made of linen. It is finished with two hand-whipped buttonhole style grommets for attaching to a pole.
The flag is in good condition with some expected yellowing of the white stripes and some minor insect damage to various parts of the wool body and a few small stains. There is an expertly hand-sewn contemporary repair on the 8th stripe down (a white stripe) near the fly that is done using wool taken from identical bunting that is nearly invisible.
Although the 30 star flag was official from July 4, 1848 to July 3, 1851, this flag exhibits traits from a later period. Specifically the sewing technique of the stars is a late 19th century technique. In addition, although the sewing machine was invented by Elias Howe in 1842, flags were not routinely made using machines until the 1860s and later and the stars were not sewn by machine with any regularity until the 1880s and later. Machine spun mercerized cotton thread began to be made in the late 19th century. This flag appears to have been professionally made. However, by that for the period I mean the pieces for each flag were cut at the manufactory then bundled and given out to individual seamstresses who were paid by the piece for the finished flags. There were some differences in the individual flags made for each manufacturer. In addition, the use of fine English bunting suggests the flag is a product of a professional flag manufacturer.
Obviously from the features listed above the flag was made much later than the 30-stars on the flag would suggest. The 30th state was Wisconsin (admitted May 29, 1848) and it is possible this flag was made for the 50th anniversary of that event in 1898. Alternatively it may be that this flag was made in the 1880s or 90s by a piece-worker who left off a row of eight stars at the top, which is not unknown. There appears to almost be enough room at the top of the canton for another row of stars. The 38-star flag was official from 1877 to 1890.
This assessment is based on the age of the item, it's condition and its attractiveness to collectors. As auction activity tends to be volatile, you could experience a fairly wide variation in value. I believe the flag may have a moderate to high value to Americana collectors, particularly to those who collect late 19th century-era artifacts.
I hope this assessment meets your needs. Please let me know if there is anything else I can assist you with.
Sincerely,
David B. Martucci
