[Letter.]
In: Prenten van Albert Hahn Sr. Een keuze uit zijn werk samengesteld door A. Hahn Jr. Met een toelichting tot de platen door Ed. Polak Jr.
Amsterdam, H.J.W. Becht 1928, [unpaged].
Letter, see: 1908.24.

This letter (dated November 8, 1908) to the chairman of the Central Anti- Revolutionary Electoral Association in Ommen inspired Albert Hahn’s cartoon “De buiging” [The bow], which depicted “Theo” (Prime Minister Heemskerk) bowing deeply before a smug “Bram” (Kuyper). The letter is added to a short explanation of the caricature (no. 32) in part 3 (Ed. Polak’s elucidation of the plates) of the unpaginated art book Prenten van Albert Hahn Sr.
