Subject: THIS IS FOR THE BIRDS 
Enjoying the posh and plush bird-lovers’ party at Illinois Beach State Park, 
| decided to become a new life member of the Illinois Audubon Society. 
With profound commitment to, and involvement in, rendering life more 
worthwhile and pleasurable as a combat-infantry-veteran bachelor-artist-author 
of “Spirit of Youth” (see mini-book 304-m914s at the headquarters building of 
the free Chicago Public Library), who survived turbulent and terrifying years 
of the World War II in which 22 million were killed, | would like for bachelor 
men and women and others living in this war-torn world get it all together 
by learning and enjoying universal secular art of loving one another. 
Let future historians write in Illinois history that we participated in tran- 
scending all barriers in honest endeavor for songs of birds to be heard through- 
out Illinois evermore.
