Certified plate proofs are the last printed proof of the plate before printing the stamps at the Bureau of Engraving and Printing. These plate proofs are each unique, with the approval signatures and date. For postal scholars these plates provide important production information in the plate margin inscriptions, including guidelines, plate numbers, and initials of the siderographer, or person who created the plate from a transfer roll.
This plate has "wrong color" written on it and a die proof of the stamp attached with the correct color.
