I wonder what Jack Hill thought of Peter Max?

I became aware of Peter Max when I was in grade school. I loved his work then, and I still do now.

I purchased a big Peter Max book that I let Jack borrow to look at it while he was confined in the hospital.

I will have this big book at my gallery opening and would hope that every visitor felt comfortable enough to sign their name and/or write a note....sort of like a yearbook. Before I left that day I considered asking Jack to go ahead and write his note inside if he wanted ...but I didn't. It was the last time I saw him.

What kept me from asking?
