From Detective Comics #168 (February 1951), both by Lew Sayre Schwartz and George Roussos.Again, Batman might be same figure, otherwise different art.
Another Charles Paris Detective cover, from January 1948. The splash page is the same art with the usual minor color changes.
Our Army at War #20 ,March 1954, sports a cover by Irv Novick which mimics the splash panel by Jerry Grandenetti and Bernard Sachs . Slightly differing POV and colors.
At first glance Joe Kubert's cover and splash page for Our Army at War #138 (January 1964) appear identical. Closer inspection shows several differences..the position of the Private and his sleeve damage for starters.
Superman #91 (August 1954) has a wonderful mirror image, new artwork cover/splash combination, both by Plastino. Supes even punches with different arms. Makes you wonder why they didn't just use a real mirror image, maybe in 1954 it was easier to just redraw it (?)
