Extremely rare 1960s pinback button

I specialize and deal in rare pinback buttons this is from the '60s and is very well made and crafted. This would be great for a teacher to wear or really for anyone to wear but seeing the Apple it reminded me of a teacher. Mine is the only one I see on the internet. Because I usually search because I like to carry two of everything just in case someone wants one after I sell the first one.
