I love creative people who plough their own furrow Charles Harper appears to be in that category, really liking you stuff too your abstract/minimalist photography has inspired me, as poorly as I tried to follow you in that, the artistic stuff of late is completely beyond, I had fun trying though..
I have this book. It was a subject of one of my 365 posts too. ❤️ Charley Harper. He was from here (Cincinnati). I met him back in the 90's when I was President of the Art Directors Club and we gave him a Lifetime Acheivement award. http://365project.org/yogiw/2017/2017-01-03@yogiw
