Captain Marvel Autographed Picture from His Comics

Here's an awesome Captain Marvel autographed picture that was featured in the pages of Captain Marvel Adventures #13 which first published on June 26, 1942.  I wonder how many kids carefully removed this picture and proudly hung it on their wall!!

I also like Cap's "Yours for old Shazam" right before his signature - if I remember correctly it's also how he would sign the fan club letters.
