Over at the SilverAge_GoldenAge Yahoo Group, I managed to identify 3 of the covers: Cat-Man Comics #24 (May 1944), Wonder Comics #10 (Feb 1947), and Amazing Adventures #2 (May 1951). The banner itself contains 1 giveaway: Exciting Comics #45 (March 1946). Ben Samuels identified 4 more: Dear Beatrice Fairfax #6 (March 1951), Startling Comics #49 (Jan 1948), Real Life Comics #12 (July 1943), and Speed Comics #35 (Nov 1944); leaving 1 unidentified. Yoc took pity on us and revealed the last was Captain Easy #13 (July 1948). Some of these were not credited at the GCD, so I've submitted indexes of those covers. Thanks to all!
