Sorry for not posting more recently. I've been immersed in a new book on General Albert C. Wedemeyer.
One cannot discuss the history of the Boy Scouts without referencing their magazine Boy's Life, begun in 1911. The Boy Scouts have issued a number of more specialized periodicals, but Boy's Life is their flagship.Early issues are exceedingly rare. Rockwell's first ever magazine appearance (December 1912) and his first magazine cover (unsigned September 1913) are highlights.
I had Rockwell sign a copy of this for me and traded it away.
I still own the first three issues and a volume from 1914 that was art edited by Rockwell (his first job in illustration) that contains dozens of his illustrations. Rockwell did illiustration from the magazine well into the 1970's. I don't believe that there has been a longer association between an illustrator and a magazine in publishing history.
See you again soon.
