Original period design with running numbering starting with the numbers 037,..., diagonal black overprint "MODEL" enclosed in a frame.
Chracteristic typeface in the overprint allowing the design to be considered original.
Paper loss and delamination in the left margin from tearing, probably from an individually prepared checkout pattern.
Broken twice by the field.
Scattered creases and pen annotation on the reverse.
Original Viennese brand patterns are rare and underappreciated qualities.
