Canadian ESB 21-Back: Here you see the Canadian version of the ESB 21-back, the first of the blister cards in the ESB line. The front is notable for its bi-lingual version of the "secret figure" offer starburst and the small black rectangle below the company logo, which bears the address of Kenner Canada headquarters. Additionally, the top right corner features bi-lingual text.

The back includes more unique features, namely a French version of the ESB logo and French text.
