Description:

"MINIATURE SHEETS": 3d sheetlet from the upper-left of the sheet, CTO with the Exhibition cds x2 strikes of each in red & in green all of 29OC28 being the First Day of Issue, full unmounted o.g., Cat $500++. Superb! This is the only sheetlet we have seen with the green cds in conjunction with the red cds.

For many years, successive editions of the ACSC referred to cancellations in red or "green", with no reference to blue strikes. Consequently, the common blue impressions were routinely, and erroneously, called "green". The 1994 edition was the first to list all three colours. The catalogue value of $500 is demonstrably conservative; at least two examples have sold at auction for more than $1000.
