X-Men #5 (1992) Omega Red, Maverick
This book features the first Omega Red cover appearance and the 1st appearance of Maverick. It's created by a bunch of all-stars: Jim Lee and John Byrne (story); Jim Lee and Scott Williams cover and art. What a killer book, and underappreciated relative to issue #4. This book is graded 9.8 NM/MT with white pages by CGC.
