Attrib. Thomas Birch (Pennsylvania, 1779-1851) miniature portrait pin, enamel on copper, circa 1820s, depicting General Andrew Jackson of Tennessee, possibly after the painting by Joseph Wood. The Wood portrait in particular was commonly reproduced on Jackson's presidential campaign memorabilia, and it is possible this pin was intended to be worn on a campaign ribbon. A note found with the pin notes that it is signed "Jackson" en verso, but we have not attempted to open it. 1" x 7/8" in a gold frame marked 750 verso. Provenance: The estate of Dr. Benjamin H. Caldwell, purchased from a Virginia dealer in 1995, and, according to Dr. Caldwell's notes, authenticated by the Philadelphia historian Marian Carson. An article about Birch in The Magazine Antiques, September 1933, features a list of his portraits which includes a likeness of Jackson made "in 1820". CONDITION: A couple of very light small scratches/abrasions to background, overall excellent condition.
