Once again, picking up my very forgotten series...
|Illustrator: Louis J. Rhead. Christmas 1894|
|Illustrator: Harry Whitney McVickar. March 1896|
|Illustrator: unknown. February 1904|
|Illustrator: George Barbier. February 1916|
|Illustrator: unknown. March 1916|
|Illustrator: Gustav Michelson. April 1916|
|Illustrator: Erte. January 1918|
|Illustrator: Erte. November 1920|
|Illustrator: Erte. November 1926|
|Illustrator: Leon Benigni. March 1932|
|Illustrator: Erte. December 1932|
|Illustrator: Erte. November 1933|
|Illustrator: Erte. March 1935|
A large number of these came from this great blog post. I think I love Erte's covers the best, especially that one from January, 1918....but that really early cover from 1896 is pretty killer, too.
p.s. - I know that some of the "unknown" illustrator covers have a signature, but they're too small for me to make out. If you know who illustrated any of those, please let me know!
