Corinphila Auction 284-290 Day 1

1934: Kaieteur Falls 4 c. slate violet, a used vertical pair, variety "Imperforate Horizontally" with clear margins at top and at base where the stamps have been separated manually, of excellent fresh colour and lightly cancelled by 'Air Mail GPO / British Guiana' datestamp (April 18, 1937) in black. Extremely rare. Cert. Brandon (1996) Gi = £ 23'000.rnNote: The Dale-Lichtenstein collection contained two blocks of four and a marginal pair of this variety (lots 634-636). In the sale catalogue, Sidney Barrett of the Economist Stamp Co. stated that, from the original sheet of 60, 42 examples were sold as singles and the remaining eighteen from the three left hand rows were saved - this leaves nine pairs of which Dale-Lichtenstein owned five. Towsend & Howe (pages 148 and 149) differ somewhat in their opinion but the figures remain approximately the same: 26 or 30 stamps were sold with 8 or 12 sold to a local clergyman who complained that he had to separate the stamps. This pair presumably sold over the counter as separated by hand prior to the error being noticed and the remainder of the sheet being sold. Photocopies of the two articles are attached with the lot.rn
