I can’t believe it was 41 years ago but in 1975 I went to Cleveland, Ohio for a training class for Automatic Sprinkler to learn how to design fire protection systems. While I was there, I visited the Cleveland Museum of Art and took my drawing tablet and an art box with pencils, charcoal, etc. I was able to sit down in front of Ruben’s portrait of his son and fell in love with his work. I checked and it must have been a visiting exhibit because it isn’t in Cleveland now.
Here is his original drawing. In this work, he used only four colors – black, white, red and brown Conte Crayons on toned paper.
