vintage crochet afghan or bedspread, retro acrylic rainbow color blocks w/ black

I love the beautiful colors of this 1980s - 90s vintage afghan. It's thick and heavy, all acrylic yarn, hand crocheted. Measures about 64" x 78" overall.

This is very nicely made, yarn ends woven in neatly, looks almost as good on the back as the front. It's nice and clean without pilling or wear, I don't believe it's ever been used.
