Thanks Joe for the pics - I will have to wait till I get an older head - but just looking at yours - I do not think it is a alter ego head.
it looks white-ish not the mocha that you and the MM talk about.
But it is mego - and also blank on the neck.
I can only guess at this point - but maybe it is the Don (dyna boy friend)
either way for 5.00 I can't complain - and it came with a bunch of other mego parts, original batman belt, robin gloves and some other odds and ends.
I plan on going to mego meet next year - I will bring it with me and show it around to see if anyone knows who or what it is.
Thanks again for the help/info.
