I have one of Don Miller's reference prints in a frame just a short distance from where I'm sitting.
Obtaining that was part of my reviving my printing activity, after I had to put that activity aside for awhile due to a too busy life.
RIP, and condolences to his family and friends.
According to his wife's Facebook page he died on January 11, 2024. She shows the date in EU notation as "11-1-2024". She also posted on Feb 11 that it had been one month. Easy mistake that all of us Americans could make!
