If it becomes as useless as "Eames Era," I'm sure I'll come to hate it, but for now, I count it as progress that an eBay seller tries to rope in business by calling something "Creative Playthings Era."
It certainly got my attention on this sweet, biomorphic, slot-together plywood chair/rocker by a company I've never heard of before: Master Woodcraft, Inc. No date is given, but consensus in the mid-century design academy says the "Can't Sell A Child's Chair Without A One-Puppy/Clown Band Painted On It Era" ran from the late 1950's to the mid-60's.
