I am unsure of what this poster is actually as I've had it in my collection for years. It has 10 images that all depict Pete Rose three different ways; Swinging, Sitting, and his famous pose pointing to the crowd after his hit to pass Ty Cobb. 

I suspect it is the artwork used on the tickets for his restaurant the Ballpark Cafe in Boca Raton, Florida.

It is printed on heavy paper stock, but not as think as a baseball card.
