The wall returns to being a painting. The exhibition consists of two mural artworks at the HAM gallery. These works are be composed of layers of colour produced with a stamp and ink. The stamp patterns form an optically blended colour surface with a structure that becomes clear on closer inspection. The idea behind these works is human communication and the signs and symbols that are used for this. We usually take these so much for granted that they become almost invisible. When reading words we rarely stop to look at the form of individual letters. Although the ink used in these murals is visible, the monotone colour surface conceals stamped markings, just as invisible ink hides a message in paper.
