Bauhaus Prisma & Prisma Bauhaus is a fusion of the multilined Prisma and Bauhaus-like letterforms, in 16 variations plus 6 shaded styles. Futura Prisma & Prisma Graphic is a related series with more conventional basic forms (like in Futura), e.g. with diagonals in ‘AMNY’. Apart from these differences, Prisma Bauhaus is equivalent to Prisma Graphic (with open ends in the basic style), while Bauhaus Prisma is equivalent to Futura Prisma. Harrison Bauhaus is a spin-off with distorted lines.
