for sale/trade: '58 topps jim brown rc for '55 topps koufax rc
 

i bought 2 of these for a signing but decided to go with the nicer one.

i would like to trade this spare for a koufax. we can do straight across in same condition, or i'll throw in some cash for a little nicer (fair/good range). the brown was in a psa 1 holder.
