Holstein works are on the border of comics and illustrations. They have a message to be told and within the picture one can discover a complete story even fantasize about the figures and what they are doing. It is a kind of art which is timeless and easy to admire. Figures and drawings are detailed without being realistic. As said a bit like comics are drawn and made.
The Stedelijk Museum recognized the qualities of these drawings in an early stage and made a beautiful catalogue together with the exhibition in 1970. The SIPKE & PIET boek is a typical Holstein production. Drawings and design ( WIm Crouwel), make this a highly collectable item.
