Burnett's Cooking Extracts, Boston Mass., 24c Violet (EP57). Stamp with deep rich purplish color and detailed impression, case is a lovely golden brown color with part of original silvering on reverse, according to the P.F. the mica is replaced, which caused them to issue a certificate declining opinion as to whether the stamp is original to the case, Extremely Fine appearance, considering this encasement's provenance and the positive opinions of other experts who have examined it (including the experts at Stack's and Heritage who catalogued the Ford and Mayer collections), we question the P.F. opinion -- nevertheless we are compelled to offer it "as is" -- the Ford sale catalogue (Stack's 6/23/2004, lot 447) suggests there are only about two, at most three, 24c pieces known, with 2013 P.F. certificate stating that "we decline opinion as to whether the stamp is original to the case"
