This comic has the origin of Supergirl and an preview advertisement for Green Lantern #59, which is a key issue, the first appearance of Guy Gardner. It is missing the front and back covers. The staples are rusted, pages are browning, there is major spine split at the bottom of the pages, corners are damaged, etc. The comic may have little to no value in this condition. I’m not sure what this comic is worth in this condition, with the Supergirl appearance, and the preview ad of Green Lantern. It may be priced too high or too low. Feel free to make a Best Offer. Action Comics Superman #360; Supergirl Origin; Preview Ad For Green Lantern #59 1st Guy Gardner. I wanted to have the title look like the above, but there weren’t enough characters.
