Marvel Universe Series 3 4-card Diamond Previews variant promo sheets

Both these sheets contain the Diamond Previews logo on the sheet backs but differ slightly in that one is wider, containing more text info about the actual set. These are just two of the four variant promo sheets for this set. The third is the limited edition sheet (30,000 made) which contains the Impel logo in grey on the card backs, replacing the Diamond logo; and the fourth contains the CBPG logo on the card backs.
