I can't believe it's been 50 years since the 1st Corn Hill Arts Festival. And I was around for most of them. As a matter of fact I created or helped create a number of the posters. The Corn Hill neighborhood has published this wonderful book of all the posters with some history and comments by the artist on each one. It is only $20.00 including sales tax and is available by contacting https://cornhill.org/.
Oh, by the way, I also created the cover for the book.
