Similar to the work in the Centraal Museum, Utrecht. Peter Strucyken in May 2018: Ger van Elk's work TPPW 15 is comparable to the work from the Centraal Museum in Utrecht, made with the same computer program, version TPPW 15, but it is by no means the negative of it. January 24 is mentioned on the drawing, that date is correct. Data is important because it makes it possible to determine the order in which the drawings were made. The title refers to the program. This drawing is therefore an original. I did not make copies of drawings, but I did sometimes make different versions with the same program. The drawing you have is one of my favorites. It is, I think, one of the ten best that I've made. And there are several hundred. Ger van Elk had a good eye.
