“Corkey’s Carnival Caravan” 4 pair of sides for four 50-footers printed full color on cardstock. Each car shows a marching band to the left of the double doors and advertises something different to the right. If you don’t want to make your own boxcars, simply glue or cement them to another boxcar, or buy old boxcars on Ebay that have usable underframe, trucks & couplers
