£2,000 - £2,500

1910-13 2s, die proof of frame in black on wove with die number ‘4522’ at upper left, blue crayon cross at centre, and printer's reference number erased at upper right (just affecting the design). From the printer's working day book (the so-called ‘dirty’ proofs) and unique thus. The printers prepared two sets of master die proofs. One set, the 'clean' proofs, were kept in the firm's offices. The second set, the 'dirty proofs, were in the printer's working day book.
