I was really excited that I was actually able to find something about the maker of this trick via MagicPedia:
Theodore L. DeLand, Jr. (1873- January 25, 1931) created the phenomenon of packet tricks between 1906 and 1915, during which time he marketed almost 100 tricks using gimmicked cards and decks, many of his own unique creation.
DeLand was a clerk at the U.S. Mint in Philadelphia and died in a hospital in Norristown, Pennsylvania.
DeLand's tricks involved the following principles, some of which he was the first to introduce:
* Double-faced Cards
* Double-backed Cards
* Specially Marked Cards
* Printed Fans
The large instructions are actually printed onto an envelope that contains dozens of cards that have the great back images I have pictured, even though the instructions only call for the use of three cards.
