I came across this paragraph in an issue of
The Carto-Philatelist from
“While examining an old Scott’s Monthly Journal for November,
1962, I found a picture of what I believe is the first map watermark.
It appears on the current Cyprus series issued September 17, 1962, and
has a clear map of Cyprus together with the initials KC and KD, the
“D” being the Greek delta, a triangle.” Harold B. Howard
I ordered a series of 11 stamps (206-216) and they do
in fact have map watermarks! Of course, the question is," How do you
preserve the image of the watermark?” For the web page that is
relatively simple. You scan it and use the scan. So...here it is.
The island of Cyprus is
quite clear near the center of the stamp (left as you view it, and
reversed because we are viewing the watermark from the back). The
initials are also fairly clear (also in reverse).
