The explosion in the fifth panel looks to be all Sal, to me. But the two artists worked so well together in the '70s, and this is a really nice page.

Thanks Paul! The split of chores between Sal Buscema and Frank Giacoia may be impossible to sort out precisely, but we have another interesting point of reference with Avengers 73, where Frank Giaccoia was credited as "Artist", and was teamed with Sam Grainger as "Embellisher", all in all a somewhat clearer definition of roles. In any case, in this issue, the overall page grid allows for larger panels and, on some pages, figures are rather stiff. So, the debate is still open, but it's clear to me that Sal Buscema's pencils have been essential on this very page!
