I made this board some years back its a 4'x4' made of 4 2'x2' 1'' foam tiles.As you can see its a valley of sorts with cliffs around it. I made a number of trees and bushes to go with it see pictures below. This board appeared in the Infinity tournament during the War Store Weekend in NJ a few years ago. I'm looking to sell it to make space for my London board. What do you think I should ask for it?
