Grading Recommendation
Not recommended for professional grading. The cost of CGC/CBCS fees would likely exceed the underlying value of the comic in this condition. It is a great 'reader' copy or a place-holder for a Silver Age collection.
Notable Features
Second appearance of the Silver Age Clayface (Matt Hagen). Notable for the 'Batman becomes Clayface' transformation subplot. 12-cent cover price variant.
Authentication Notes
The comic displays authentic 1960s newsprint aging (tanning), correct 'Superman DC National Comics' 12-cent logo, and era-appropriate staple placement. No signs of restoration or modern reproduction are evident.
