Vintage film envelope from The Calvin Art Shops, Whittier Boulevard, Los Angeles, California. The film was size 116, which was introduced by Eastman Kodak in 1899. One roll cost 10 cents to develop and enlargements were 6 cents each. No date is written, but this was found with negatives that matched photos dated from 1904 & 1906. I am unable to find any other envelopes from this company, anywhere online. Measures 4.5" X 6.5" when folded.
