Louis Prang
Q The American printer and publisher Louis Prang of Boston had the convenient habit of usually dating his commissions; this trade card was published in 1881 posing the query as to whether he changed his trade card each year. Can other collectors confirm or deny this?
G.E.M.
A The first trade card below for Prangs American Chromo’s has no copyright marking, while the other card states “Copyright 1879 by L. Prang & Co, Boston, USA.”

It’s my observation that Prang invariably prints the copyright date on their output, particularly in the case of greeting cards.
