Your sample is a bit low-res for an accurate match. It closely resembles Optima:

But I haven't been able to find an Optima-like typeface with a left-facing serif at the apex of the A.

These two fonts (which are basically identical) by Steve Jackaman also come close:

Same for this font, which came bundled with Windows 7:

Thank you. This was really useful.
