SG D3a is the listed variety of the 2p red, black and light apple-green Isle of Man postage due stamp, with a positive offset of the red printing on the back.^[1]

The underlying stamp, SG D3, belongs to the first Manx postage due series, designed and printed by Questa using lithography. Perforation is 14½ × 13½. The issue was produced in sheets of 100 (10 × 10), with plate numbers 1A and 1B, each ×3. Imprints appear in the right-hand corner of the bottom margin and the left-hand corner of the top margin.^[1]
