From Marvel Team-Up #64, December 1977. Corner box Spider-Man first appeared MTU #56, unsure of artist; Misty Knight: probably John Byrne (?) pencils & inks.
^ Credits are my speculation, based on related credits from Grand Comics Database--Byrne did MTU 64's interior story, for instance (also thanks to @ls78ftw2thaend for the Byrne suggestion!)
(Corner box Spidey looks closest to work of Dave Cockrum & Al Milgrom to me--their Spidey in MTU 59 cover art, for instance. That head first appeared on MTU 56 though and it doesn't clearly look like the work of the interior or cover artists on that issue to me so I dunno. 'p')
