Presidential Series Washington experimental plate proof
The Bureau of Engraving and Printing produced this experimental plate, incorporating Elaine Rawlinson’s winning stamp design for the 1938 presidential series and five other designs, from which President Franklin D. Roosevelt made the final selection. Rawlinson’s design, seen in the top two rows of each pane, captured the president’s imagination.
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.
