Here’s a 1969 Topps Cello Box Proof Sheet. Notice both the purple and red box variations on the single sheet.
The sheet was described as a large 29” x 38” uncut final process sheet that contains six complete 24 count ten cent 1969 Topps display boxes, with each box containing the color photos of Willie Mays, Carl Yastrzemski, Bob Gibson, Pete Rose, and others. The sheet was folded down and across at the center over the years and was listed as in VG condition.
Here are examples of both 1969 Topps cello box variations.
