Front Design: Three cards, size by side, duplicating the 1962 Topps (and thus 2011 Topps Heritage) card design. This means the panels are 3-1/2" tall and 7-1/2" wide. The 2011 Topps Heritage design features a grainy photo, usually posed, which is made to look like a sticker or poster peeling off a wood-grain panel.
Parallels and Similars: The original 1962 Topps ad panels looked essentially the same, since the card design was the same. The original ad panels also had blue panels advertising the product.
Distribution: Randomly inserted as box toppers in 2011 Topps Heritage hobby boxes.
Thoughts: I'm not a fan of Topps Heritage. I don't have anything against it; the set just doesn't fit my collecting interests. I think these ad panels are great, though, and if Heritage had been inserting these since 2001 I would put together a special type set for display. Alas, they have only been inserting them since 2008.
