Instructions
Search antique stores for old cigarette cases. Cigarette cases were most popular during the 1920s and '30s, with some continuing popularity through the '50s and '60s. Your best bet is finding antique stores that specialize in these decades.
Diversify your collection. Old cigarette cases come in all shapes and sizes, and your collection should represent the aesthetic variety of the medium. For instance, 1920s cigarette cases were often made in the Art Deco style, appearing geometric and modern. Later cigarette cases, such as those from the 1950s, were less glamorous and often quite simple. Try to collect a few cigarette cases from each decade.
Take good care of your collection. Old cigarette cases can appear rusted and worn-down after decades of exposure. Use a soft cloth and a fine metal polish to keep your old cigarette cases looking their best.
