Well I'm not sure if this is of the wall but this was my idea for this year.
My girlfriend works at a print shop, so she can make stickers and labels and such. So I'm having her make label that resembles the Budweiser or beer logo with our league name, the year, winnining team name, 05-06 Champion.....you get the idea. And place it on a 40oz bottle. Then have similar labels for 2nd and 3rd place....have 2nd on a 22oz and 3rd on a 12 oz. Hand them out at the awards party(for us usually during the Superbowl) and drink up!
Maybe not as cool as an engraved traveling trophy, but at least you can take it home and keep it as a momento on the mantle(if the old lady will let you).
Congratz on your win!! (I won with LJ and Palmer....that 40 is gonna taste sweet...well at least its beer).
