Time to revive this thread again. The other thread is
more or less about the engravers http://goscf.com/t/9106
and this one here I gather is just about the beauty of engraved stamps with no emphasize
as to who the engraver was.
Just the other day I was going through some of my FDC and noticed
this Swedish one from 1968 portraying wildflowers and was
again struck how a simple mono or bi colour engraving can make
a flower looks so attractive.
Actually after buying this FDC around 1970 I started collecting
Swedish stamps, primarily because of the engravings not
because they were engraved by Slania, who I had never heard of
I always meant to get the MNH booklet but never did.
