The Bröhan Museum (p. 38) is known for its collection of Art Nouveau, art deco, and Berlin Secession works, which are defining art movements of the late 19th and early 20th centuries. Aside from this focus, the museum’s Blackbox series also highlights graphic designers and photography. Blackbox’s second installment features Günther Kieser, one of Germany’s most prolific graphic designers. Kieser is famed for his posters created for jazz and rock concerts, and his venerable work includes the psychedelic poster of Jimi Hendrix with cables growing out of his hair, as well as the poster of the colorful grimacing skull for the Grateful Dead. Although Kieser is now in retirement, he made an exception for the museum to design the promotional poster for Kieser, Posters, which runs until 23 July.
