That French Polynesia is a perfect example of what was achieved
on the TD3 Chambon press.
Although they hadn't yet perfected colour separation looks like.
Apropos the painting itself, another one of Paul Gauguin's
masterpieces.
But when one compares the stamp with the actual painting
then it's obvious that no matter how good the engraver
cut the die or how well it was printed there is just no comparison.
In my opinion offset/litho or photogravure lend themselves much
better for printing paintings on stamps.
I believe that the Austrian State Printer achieved more realistic
results with one colour (engraved) and multicolour photogravure
when it comes to portraying paintings on stamps.

PS Have you seen the movie in which Kirk Douglas plays van Gogh
and Anthony Quinn acts like I imagine Gauguin was in real life?
I wish there were still actors like that around.
