So kudos to Berlin's Kunstgewerbemuseum (the museum of decorative arts and design) for putting writing on the wall that no one can miss, and winning a design prize along the way. The eye-catching size and color of the signage creates a certain aesthetic effect that not all museums would want, but it accords well with the all-parts-visible idea behind Rolf Gutbrod's 1960s building.
Even award-winning signage has two potential weak points, however. First, it has to be wriiten in a certain language—here German, which some visitors may not understand. Second, there is a compelling argument (nicely presented in an airport example in the addictive design podcast 99% Invisible) that the architecture itself, not just signage, should help guide the people in it. But since purpose-built buildings are not in the cards for most museums (and even if they are, wayfinding is only part of their mission), it's worth taking signage seriously.
