Dick Briefer: "U Build 'Em Blocks" Set from Playette Toys

If you know your comic book history, then you know who Dick Briefer was. In between drawing those pre-code Frankenstein comics, he did some toys, including this "U Build 'Em Blocks" set from Playette Toys. These are cardboard blocks that you can rearrange into six different Briefer-drawn scenes.

I picked this up a few days ago. Never seen/heard of this. And you know it's Briefer's because that's his signature on the box.
