Re postage stamps & chromadepth

[P3D Peter Homer <P.J.Homer@xxxxxxxxxxxxxxxxx>]

I little while back the Journal of the UK stereoscopic society came in what
I think was a "first day cover" with either a side by side or sirds image I
canot remember which but I can check as I kept it . There have been a
number of attempts at stereo stamps some of which were featured in Stereo
World although I canot recall any anaglyph versions. Types which dont
require any viewing aids at least for some people would seem to be the best
for stamps such as side by side and sirds better still the hologram types
and the lenticulars which some countries have produced although I have nit
seen any of these.  P.J.Homer
