In 1980 and 1981, Kenner produced two ESB multipacks that differed from the beautiful, preceding Special Action Figure Sets. These two multipacks were windowless, coming in small cardboard boxes. They differ from the mail-away sets as they were actually sold in stores alongside regular carded figures. Today, these ESB multipacks command prices in the hundreds of dollars. But keep in mind the figures inside were baggied, and as such, can be easily replaced.
