I get most of the names for the backs from newspaper advertising from the 30s and 40s that I researched. Below is one example from the Los Angeles Times.
The Club backs were one of the first KEM designs. They made them for decades, so there are a lot of them out there.
When KEM cards were first sold in 1935, and through about 1939, they came in the kinds of cases shown in the picture. The bottom of the cases is stamped "Neillite," which is a plastic similar to Bakelite. I call these 1st gen since they were the first. The 2nd gen cases are the Bakelite ones with the elongated KEM logo, but no emblem or circle on the top, as seen in the ad. THe 3rd gen are the ones with a more squarish KEM logo with a crown above it.
