This is my most exciting score since the vintage Oreo wrapper, and probably surpasses it because I'm such a huge Hostess Cakes fan.
This is the oldest Ho Ho's box that I've ever seen that includes the character "Happy Ho Ho." There he is on the side panel doing his Ho Ho dance!
I believe this to be the very FIRST box featuring Happy Ho Ho. The character was created in 1970 and this box has a 1970 copyright date on it. Most interesting is the fantastic comic on the box back which seems to be introducing him as a new character.
The only flaw is that this box is missing the top panel, but you won't catch me complaining.
As the old Hostess slogan goes: "Freshness never tasted so good!"
