Glenn I just finished reading your latest Dummy Stamp Newsletter
(Issue 35 - Quarter Three 2014)
and have to tell you, what an enjoyable and informative read.
You present everything so well and it's easy to follow.
Have these
User-definable Screens been used on other US stamps
since 1997.
Who was the printer?
I know that Ashton-Potter was one of the first printers to use
micro-printing.
Here is a link Glenn's site showing all the Dummy Stamp Newsletters.
http://www.stampprinters.info/dummystamps.htmAnyone who has any kind of interest in stamp printing, do
yourself a favour and check these out.
You won't regret it but I warn you, reading this stuff is
addictive and you will want to read one back issue after another.
And bingo, 3 hours are gone by.
