June 21, 2019, "EDGAR DIEHL & FRIENDS", Galerie Mariette Haas, Ingolstadt, Germany, till July 28

The gallery asked me to create an exhibition, showing my work in a small circle of friends:
ROLAND HELMER, Fürstenfeldbruck,D
GILBERT HSIAO, New York
ROB DE OUDE, New York
IVO RINGE, Colgne, D

All five of us make "Non Objective Art", taking perception as the center of our work. In the last millenium it was called "OP-Art". Younger artist have developed this approach further!
