1993's Wolverine Vol.2 #75 page 43. Script by Larry Hama, art by Adam Kubert, inks by Mark Farmer/Dan Green/Mark Pennington, colors by Steve Buccellato, lettering by Pat Brosseau and edited by Bob Harras. Wolverine showing off for the first time his bone claws after his brutal encounter with Magneto (who violently striped him of the adamantium metal that covered his whole squeleton/bones/claws).
*an idea that originally came from Peter David (R.I.P.), initially intended as a joke, until it became more serious, once the other x-writers decided to run with it, thus becoming the most shocking scene of the Fatal Attractions crossover (and also by far the most memorable fight between Magneto and Wolverine).
