Avengers, X-Men 1 - Avengers vs X-Men - Blank Variant - Neal Adams sketch & signed CGC 9.8 - Stapled - Unique copy - (2012)

This is a Very Rare Hand-Drawn sketch that was done by American comic book artist Neal Adams.
It's a nod to his famous Muhammed Ali vs. Superman action cover from the 1970s, which he did at a convention.
Neal Adams DOESN'T draw Full-Figure sketches on 8.5x11 inches sheets let alone Two Full-Figure sketches on a cover. He will only do a Single on the 11x14 inches sheets for $2200 that has to be preordered as Adams does not carry those with him to conventions. So this sketch is Very Rare and Special as Adams did Two Full-Figures on a cover space smaller than 8.5x11 inches. You will not find a Hand-Drawn Neal Adams cover sketch with Two Full-Figures on a cover. No one can get another one as Neal Adams passed away on April 28, 2022, from sepsis. €3000 would be a joke or disrespect to Amams' work and passing.
He did this after we met in 2012: https://www.nealadamsstore.com/Batman-2--CGC-98-Drawn-on-Batman-New-52-0-Blank-_p_891.html
