Correlation is not causation; Marvel comics in general had their highest sustained monthly sales era at the same time. Did X-Men #1 break all sales records because Spider-Man was married? It was the beginning of the speculation bubble—Spider-Man #1 was a new number one, written & drawn by the most popular Spider-Man artist of the decade, it had multiple covers. There’s as much evidence that the cover having a Spider-Man crotch shot is the reason for it being the best selling Spider-Man comic as the marriage.
