Ascension 1924-33 2d grey-black and grey, SG13a, upper left corner block of 4 with plate number "1", from 1924 first printing, showing variety "Broken mainmast" on R2/1.
A fresh and fine positional multiple of this beautiful King George V stamp. Three of the stamps, and most importantly including the variety, are unmounted mint.
Very scarce in this positional form and of such exceptional quality. A real gem.
