Little Weirdos that there were Diener erasers that look just like these guys.
Neato Coolville, the Diener figures were made in different degrees of hardness. These Popeye figures may just be made of the hardest material they produced. Not effective as erasers, but let's face it, none of us used these things as actual erasers, they were useless as such!
UPDATE #2: Reader Alan C. emailed me to inform me that these figures are Popeye's Chicken Kid's Meal toys from the eighties. Makes perfect sense, considering Diener's association with fast food restaurants, and, well, Popeye/Popeye's Chicken. Unfortunately I also learned there is a Poopdeck Pappy figure, so now my collection feels incomplete!
