How to set the font in an Org-mode buffer?

Question

Is there a simple way to set the font used when viewing an .org file, so that it applies to that file every time you open it? I'm imagining something with the properties, like the imagined example below.

I'm sure there is a way to do this with Emacs Lisp, adding to org-mode-hook and programmatically setting the face text property or something like that. But before I do that, I wanted to check if there was a simple way, without writing Lisp code.

I understand that typical users of Emacs do not care about this kind of thing. Like most people, I use it primarily as a code editor, but sometimes I care what my text looks like on screen and want to play with different fonts.

#+FONT Helvetica Neue, 14pt

* Uno
* Dos
* Tres

Buffer local faces (including the font family) can be set using the function face-remap-add-relative, which sets the variable face-remapping-alist. org-mode files can have file-local settings such as placing a snippet like this at the top of the file:

# -*- eval: (face-remap-add-relative 'default '(:family "Courier" :height 160 :background "yellow")); -*-

OR

# -*- eval: (face-remap-add-relative 'default '(:family "Monospace" :height 160 :background "yellow")); -*-

NOTE: Emacs expects :family, not :font, in this particular example.
