I work for SCP and a guy got in touch with this. He bought it at a local auction decades ago. I cannot find anything like it on the interwebs, nor has my boss at SCP. It's an original printing plate for a '38 4 in One. Last photo is of the card. Click on the image and it takes you to my Flickr page, where you can see other photos.
Please chime in if you have seen similar. Thanks.
