Captain Marvel Comic Covers Cross Over

I've discovered that there are at least two Captain Marvel comic covers that crossed over from the golden age of comics to the 1970's Shazam! comics!

The first example is Captain Marvel Adventures #45 (published March 14, 1945).  A similar cover appeared on Shazam! #4 (published April 17, 1973)!

The next example is Captain Marvel Adventures #119 (published February 2, 1951).  The similar cover was placed on Shazam! #5 (published June 19, 1973)!

All four covers were drawn by C. C. Beck!  As I come across any other cross over comic covers, I'll update this post!
