how to get it?

This one is Tiki Palms by House Industries, available for licensing on on their website.

Tiki Palms is close, but it’s not exactly the one from the sample, is it?

Your image is part of an alphabet, so that begs the question what is the source (often a help in these queries)?

Very close is Patrick Broderick's Castaway - a recreation, it would seem, of a typeface that appears in the predigital Solotype Catalog as 'Confucius'. Your image, though, contains some differences in detail.

Crap ... after posting the above, I wondered who the hell had credited the identification to someone named Sven Viking - who didn't even make an appearance in this thread.

It turns out that Sven Viking was the original poster in this 2011 thread - who posted the same image as Samu.

Obviously, there is no exact digital solution to this thus far. Unless it's the elusive bamboo.ttf that Sven alluded to three years ago - and our moderator has not clued us into ...

In my folder labeled Bamboo fonts I have five - one named Bamboo2 is the one you are looking for - no credits when examined in FontLab info. The five all came from free sites, check Dafont and AbstractFonts.

Sorry, I checked it was not from AbstractFonts or Dafont
