Hiya Chris! Congratulations on your recent marriage! May she always be a gem mint '52 Topps Mantle to you!
I have never seen the image of Mick you posted. It's a beauty. From the photo and artwork graphics, I would guess 59 -- 61. Perhaps it was once part of some advertising display. Regardless, the piece was nicely cut and preserved all these years.
Hope someone comes through with identifying it. You could contact Tom Bartsch at Sports Collectors Digest to have them print it and see if any of their readers might know. Some of those old-timers might not indulge in Net54. If you feel so inclined, contact him at 800-726-9966 , ext. 13815.
Take care, my friend. --Brian Powell
