lot of vintage plastic deer, unmarked Christmas reindeer figurines, Rudolph hand painted red nose

Lot of five vintage plastic deer or reindeer - these were used as reindeer, one has a hand painted red dot on his nose! They are not a brittle sort of hard plastic, but not really rubbery either. Solid.

These are not marked at all that I could find, which I thought was a little surprising. I'm guessing these are probably older (maybe 60s or 70s vintage?) When pieces like this were more likely to be marked with a label than in the plastic mold.

There's no breakage or cracking to any of these, all five deer are in very good condition, just a little finish wear from handling. They are about 3 1/2" long, about 4 1/2" tall.
