Is this the Ron Lewis Piece? Sounds like it. You called it a plaque... so what is the size of yours (dimensions in inches?) This piece is usually found in the form of a very large poster or lithograph.... over 3' wide.

If authentic (and neatly signed in uniform ink) this piece can command over $1,500. More commonly, it goes for about $900 - $1,100 with one or two players sloppily signing (and subsequently devaluing the piece a bit). It's pretty rare to find it signed by all 11 in uniform strength, and vertically along the leg.

If yours is a smaller plaque version of some sort, it isn't worth as much money. The value also depends largely on whether it's authenticated (and who's LOA accompanies). Post a photo if you can...

Hope this helps!
