Here they are, the control blocks of South Africa’s eighth definitive issue of postage stamps.
It turned out that my blank album pages outfitted with three vertical pockets, were the right size to the millimeter for the height of the blocks.
So I went with a layout that tiled the smaller blocks sideways onto the page.
(I am still deciding if I like it).
The full sheet of 5c stamps is a reprint of the original 2010.10.27 issue (dated 2011.09.01). Reprints of the other original prints exist, which I don’t have— and that’s O.K.
