Fisch, its fine to disagree and discuss. the last time somebody disagreed with me regarding my comments on auction results for OA, I spent considerable time preparing my point by point response and the result was a lot of agreement.
I base my comments on numerous factors, as you do with yours. Given I am not in the best of health, I would be happy to discuss with you at a later date, point by point.
FYI, the last Byrne X-Men page sold for $56K, if I recall correctly. Perhaps you are thinking about another one? Most Likely the page from X-Men 137?
