Four pages from this story were sold on Heritage over several years, and the identification of the artists is different for each listing – and none of them are quite right, it seems. I got this one from Heritage in 2015, and it was listed as all Dick Giordano. My brother recalled the full story, as told by Joe Barney (and then found in Bryan Stroud's interview with Joe Barney in 2019).
Joe Barney joined Adams’ Continuity Studio, and his first job in comics was to do pencils for this Wonder Woman issue in 1975, which Giordano didn’t have time to do on his own. Adams got Barney to do layouts, which Adams then corrected and drew over with a Pentel pen. That page was then projected onto board vertically, using an Artograph. The layouts were ‘polished’ by Barney until they could be inked.
Giordano was described as the main inker, but it looks like he may only have done the Diana Prince faces on this page. Adams clearly inked the first panel of Elongated Man and Red Tornado, and – although not mentioned in the interview – my brother identified Klaus Janson as the inker of the two figures in the lower left panel – and those lines really do look like Janson from that period. Terry Austin and Bob Wiacek, Giordano’s assistants at the time, are mentioned – but unless someone can spot them, it doesn’t look as if either had anything to do with this page. So Janson may have done other parts of the backgrounds on this particular page, with those inkers perhaps being given other pages to finish.
It was a “Crusty Bunkers” team effort in the Adams style of studio work. I think the story worked out well, and I was pleased to get one of the pages via Heritage. Thanks to my brother for sorting out the attributions (not all of which I could add on CAF).
