Super Friends Season 8, also known as The Super Powers Team: Galactic Guardians was a Hannah Barbara production in 1985-1986.
Model sheet sets were given to the animators to make sure each drawing stayed consistent between the different people that drew the different characters. This page shows the complete model sheet set for the Super Powers Galactic Guardians series.
This is an 8×10 photograph (not print) and on the back is stamped HANNAH BARBARA SUPER POWERS 1985. The origins are unknown, but since this is the opening page of the model sheet set, it’s possible this photograph was also given to employees as part of the model sheet set.
Several color prints have been found as well, with their origins unknown. Many have been found on high gloss or heavy weight paper with quality that indicates a modern print. There have been a handful that stand out as being printed long ago, with different lighter paper and ink not from a modern color laser or standard inkjet printer. While the origins are unknown, and if they do end up being genuine vintage materials, their use or origin still remains a mystery.
