Mauritius SG235a 20c Prussian Blue Die 2 Wmk Script U/M Cat 348++

The block is showing noticeable perf comb irregularities. The Bottom row has a light bend. There is some marginal creasing and a couple of faint gum tones still of very fine appearance. A scarce and interesting positional piece from the plate 28 printing (1935 and 1937). Still on the Stanley Gibbons card where is was purchased from.
