This issue has variants.
Giacoia and Tartaglione credits per Nick Caputo, who notes that both men, along with Mike Esposito, often assisted on covers together.
"Scar" Tobin, apparently, makes a one-panel cameo appearance in the Iron Man story in this month's TALES OF SUSPENSE #41 (May 1963). Credits moved, splash page reformatted with extra art added and page numbers removed for reprint.
"The Original" added to reprint splash to distinguish story from lead feature.
