Emacs face mode in local file variables

Question

I tired to explicitly set a custom face for a file using local file variables:

# Local Variables:
# buffer-face-mode-face:'(:family "DejaVu Sans Mono")
# End:

Emacs catches up these variables, not showing, however, the file with the font that was required.

How can I write down the variables, so Emacs would show files with particular faces?

Answer 1

After I found a hint on StackOverflow, that's one of the possible solutions:

# Local Variables:
# eval: (setq buffer-face-mode-face '(:family "DejaVu Sans Mono"))
# eval: (buffer-face-mode t)
# End:

Or this trick:

# Local Variables:
# eval: (setq buffer-face-mode-face (face-font 'fixed-pitch))
# eval: (buffer-face-mode t)
# End:

Answer 2

In order to make a local variable list work, don't forget that the Local Variables block has to be appended at the end of the file.
