Vernon Henkel did a lot of work for Quality! He merits an artist profile in the book. I would call him Quality Comics' second freelancer, after George Brenner. Henkel began doing "Gallant Knight" with Feature Funnies #7 (1938). This of course does not include Eisner & Iger and the three syndicates with whom Busy Arnold was partnered. Henkel is probably often overlooked because he drew very few super-heroes for any significant length of time. The Sniper might have been his longest hero run. But he had lots of other features that ran for ages.
