Safari  Suggested by Parker76 

There is a comment on this page that says "This is probably not a font" -- that is absolutely not true ... it is a font. The font is called 'Safari', and it was released in 1960 by Headliners. Unfortunately, this font was never digitized, so there is no where on the internet where you can buy it or download it.

However, there is a digitized font out there on the internet that you can buy, which is inspired by it, and it's called 'Sundowners'. Its not 100% the same, but its very similar.

I see 4 "S" in the image, and the 4 are different.
Same goes for the 5 different "R".
Same goes for the 4 different "A".
and so on...
