These color stickers -- a complete set includes 44 stickers -- were released in 1966 by Topps, according to the registry page at the Professional Sports Authenticator (PSA) website. Here are four of the stickers:
Sticker #5
Sticker #13
Sticker #16
Sticker #28
Just imagine how many of these stickers could have been plastered on books and walls and lockers by fans of The Green Hornet back in 1966.

I loved the Green Hornet. Didn't he have some type of special little gun (I can't remember what it did)?
