Early in the Super Powers line's development a series of hand-drawn pencil logos were illustrated to nail down what would ultimately serve as the final logo for all packaging, advertising, etc. A series of 24 logo drawings were completed; each offering an interesting glimpse into the logo's development.
The second image shows a close-up shot of the artwork itself. The font style varies a bit on this example, but the 3-dimensional effect ultimately used on the "stars" portion of the final logo shows up and accentuates the text.
Thanks to the foresight of a former Kenner employee, twenty-four conceptual logos among other packaging prototypes were saved from Kenner's obsolete files. The logos were publicly auctioned on eBay throughout 2010 affording me an opportunity to add several to my personal collection.
