I was gifted a huge trove of old School Arts and Arts and Activities magazines from a retired art teacher. They date all the way back to 1961. Here is a groovy ad for new ‘acrylic’ paints from School Arts Magazine, February 1971. Click photo for larger image.

Acrylic paint ad, 1971. So groovy! So many quotation marks!

Very groovy! I dig the Peter Max-ish design.

Enjoy!
