"Butch" Irvin Schramm is well known in Michigan for both his duck decoys and his simply painted "fish." His "Harlequin" decoys, so called because their patterning suggests the costume of the traditional theatrical character, are painted in bold black and white quadrants. Lacking identifying features, such as eyes and specific dorsal fins, Schramm's "Harlequins" do not represent a particular species, but are intended to catch the eye of any passing fish.

"Butch" Irvin Schramm lived in New Baltimore, Michigan, in the first half of the twentieth century (Kimball, The Fish Decoy, vol. I, 1986). He created several decoys showing the harlequin fish, named for its distinctive black-and-white stripes.
