Abstract: A blotter having a flexible blotter backing and a rigid mount with two slanted slots. The ends of the backing are mounted at two opposite side edges into the mount slots along with the edges of the blotting material. Serrations along the edges of the backing are positioned within the mount slots and bear against the ends of the blotting material. The blotter material impacted edges and the inherent flexibility of the backing provide for the firm retention of the blotting material to the mount.
