The hits keep coming. So many of the covers that S&K did for Harvey are just amazing. But this one is another of my favorites. The exaggerated perspective in the Liberty Lads are a signature style for Jack Kirby, so he is the primary penciler. S&K literally demonize the Japanese foe. This sort of thing would not be considered politically correct today, but during that war artists worked under a different standard.
I have seen penciled on the margins of the original art that this was inked by Al Avison. But that sort of notation is suspicious. I have seen an awful lot of S&K art and only on one other page have I seen a similar annotation as to the inker of the work. I strongly suspect that these notes were made by subsequent owners or art dealers. In any case at this time Avison was at Timely working as their primary artist for Captain America. As such he was very busy and it is unlikely he would have time to do this inking.
