While that already looks pretty reasonable, there are a few things that stop it looking truly vintage. One of the first things I like to do is to tweak the inter-character spacing in text (technically called the “tracking”) of the text. Modern fonts and computer typesetting seems to usually create text where the letters are quite tightly spaced, but old hand-set type was much, much looser — doubtless there’s some historical reason for this. Once you’re used to looking at true vintage typography, samples spaced in a “modern” way just jump out at you as non-authentic.
One of the really great things about Mr. Engelhardt's directions is the level of detail. The tutorial is very Illustrator specific, but by describing each step of the process he's provided enough information to adapt it to any vector-based program. I'm specifically thinking of Inkscape, a free and open source alternative to Illustrator.
