Good morning,
I am seeking some clarification.
This my have been covered but I failed to find it (so I appreciate your time)
my 09 Scott lists
#4517
Image A2138
1976 engraved perf 12x12.5
The #4596
1977-78 litho perf 12x12.5
Designs others before
Nos. 4596-4602, 4604-4607 where printed on dull and shiny paper.
So I'm lead to believe that the only difference is in the method of print? Or is there more to go on?
(Again this is from a old 09 Scott, this could be easily updated by now)
Looking at a couple of these stamps (not 100% on what issue they are, but it seems clear to me) they appear similar but not the same?
I may have missed a reissue or I'm missing something all together
Thanks for any help clearing this up
