Los 400

1936, Päts 4 S., archival proofs, strip of 3, with plate error and printing order number T.262 of the first printing of the 4 S. Päts, printing order date April 29, 1936. In 1936 the Estonian State Printing Office started to print printing order numbers on the sheet margin. Archival proofs are known to exist only for the first printing of the 4 S. Päts, not for subsequent printing orders of the 4 S. Päts. Bottom margin 27 mm wide. Plate error in Pos.91 (white error, outer frame indented at bottom right), plate errors on proofs are very rare. The perforation registration mark (cross) does not have a hole  because the proofs were not perforated, compare the perforated postage stamps in the following lot. Very fine (Hurt/Ojaste G:1, F:1)
