Trade Card for H.J. Heinz Company, "Mamma's Favorites," circa 1905

As color printing gained momentum in the late 19th century, trade cards became a major means for advertising goods and services. Americans enjoyed and often saved these little advertisements found in product packages or distributed by local merchants. Trade cards for the H.J. Heinz Company, like the one seen here, promoted its pickled foods, preserves and condiments.
