The ones from the 70's to 80's.
If anyone has any they would like to give away ( I'll pay for shipping) I'd sure appreciate it.
Condition doesn't really matter as long as they are not cracked. With or without the strap is fine too.
They have little value to me but my 3 year old son sure gets a kick out of the few I came across lately..
It's a long shot but I thought I'd give it a try...
