Flipping through a handful of Zip blocks from the '60s, I quickly noticed four different poses in which Mr. Zip was depicted in the selvage. Is there online an illustrated list of all Mr. Zip's poses? Or at least a count of the varieties?
The most common poses appears to be Mr. Zip standing upright with his left arm raised, and another with him leaning forward holding a letter in his left hand. Less common are bodyless Mr. Zips and a narrow Mr. Zip standing. Certainly I must have missed spotting others.
