Trade cards were one of the most popular forms of advertising during the 1800's and were used to promote anything from dry goods to clothing stores. Sam Loyd was approached by a number of organizations who wanted to use his puzzles to promote their goods and since he owned his own printing press he would design and print these cards. Since they were giveaways many have not lasted the hundred plus years since they were created and so The Sam Loyd Company has opened its archives to make these cards once again available in their original form just the way Sam Loyd made them way back.
