May 1990 was the 150th anniversary of the 1d black and saw the splendid
double head interpretation of the Machin design in several values
and variations, including a miniature sheet with a reproduced 1d
black. Each of the 28 items I've listed are quite easy to identify
and some are getting expensive too.
