Here is a pink vintage invoice made out to R. A. Agostini on behalf of Cahn, Nickelsburg & Co., Inc., a boot and shoe manufacturer that was located in San Francisco. The invoice, date stamped on May 4, 1914, is for a Miss. Pat. Mary Jane (I’m guessing that was a style of shoe) for $1.40. The total cost was $1.51 after postage was added.
