10-1/8x12" artboard has original pen and ink art in 8x8.25" blocked square. Art depicts full body image of Superman dropping in on two men w/word balloon reading "Hi'ya Fellas! Just Dropped In To Say Hello To All The Gang!" Art has been inscribed in ink under this "With Best Wishes To All The Boys In The Coast Artillery - Joe Shuster." As noted at bottom right art was "Especially Drawn For Golden Gate Guardian - 1945." This art was originally sent to Sgt. Mike Mikos, the editor of the Golden Gate Guardian, a newspaper published by and for the military personnel of the Harbor Defenses of San Francisco, CA. at Fort Winfield Scott. In 1945, the paper's Managing Editor was also its Staff Artist and as a cartoonist himself, this editor had a particular fondness for comic strips of the day. To provide some entertaining content to his paper, he wrote many letters to newspaper syndicates and his favorite comic creators, requesting some piece of original art that he could use as an installment in a series of mini creator biographies. Some creators wrote back to apologize that they did not have the time to help out but instead sent original art from their strips (which he could not reprint of course), some complied w/his requests. One of these artists who complied was Joe Shuster, co-creator of Superman. Artboard has two pin holes at top center of boxed art area, though these do not affect art itself. Additionally, there are two thin faint lines of soiling across art; one running across top of Superman's hair, the other running across his right arm and across "S" chest symbol and cape. While these are noticeable, they blend to a degree, almost appearing as additional motion lines. Bottom margin has blue pencil and inked production notations and some lt. scattered handling wear/dust soiling. Artboard has even lt. aging and is Fine overall, but art still displays VF. Rare and historic wartime Superman specialty art by one of his creators. Franco Toscanini Collection.
