Yes, I think he did. We were vacationing in the UP one summer and I found the same prints in nice frames in an antique shop and the only markings referred to Mr Palenske, who lived in that town. The Bear versions were marketed in cheap plastic frames, I think. I think they date to the 60s, but can't remember where I might have any verification of that!
Heck, Bill, we all know Fred was always looking for something else to enhance the bottom line. Obtaining license to use someone else's really good design was just smart business. Some of the stuff was a little cheesey, but usually he made pretty good choices. The working recurve, the bow quiver, the Bear Razorhead - those things are right up at the top. A couple of other things...maybe, not so much!
