Some stuff
If I can guess again I guess George Bellows. Or Bolton Brown?

YYEESSSSSSSSSSSSSSSSSS. Congrats. My favorite stuck-up lithographer Bolton Brown is indeed the answer.

After over 140 guesses, thistimeagain, gets the poster. Good job. Brown’s book “Lithography for Artists” 1929, is one of my favorite resources in the studio for it’s wisdom and instruction.

Thanks for playing everyone.
