Proofs are a very early print of a cardback used in the pre-production process for design or layout approvals. They are sought after by collectors because of their small population and because they can give insight into the decisions that were made in the design process all the way to production. Proofs were printed with multiple figures on a large sheet and then individually cut out. In this example we have a Series 9 / 34-Back die cut proof of Downtow in an elite CAS 95 grade. The colors are vibrant and really pop without the figure and bubble. Own this iconic piece of G.I. Joe history!  Encapsulated by CAS (95), #10168133
