The publication Aah … Aha! Albumatlas by Peter Radelfinger brings together 1562 works from the artist’s ongoing image research Aah … Aha! in small format of 5.8 x 4.1 cm. On the occasion, Michael Glasmeier has written a rambling text entitled Aah … Aha!gressions. Both artist and author understand the book as an independent work, which continues the thinking and research character of the drawing cycle and makes it visible and experienceable in its entirety.
