Grading Recommendation

Not recommended for professional grading. The costs of grading and shipping would likely exceed the actual market value of the comic in this condition. This is a reader copy.

Notable Features

Authentication Notes

The comic appears authentic based on the newsprint paper stock characteristics, the specific Marvel 'Direct Edition' barcode marking style of the late 70s, and standard ink saturation for the period.
