Vintage printable is an excellent site for exactly what you think: vintage printables. The library is well categorized and easy to navigate. The above image is from the science section.
Featured fonts are Duke (another from Lost Type), Baronesse and Barnyard. Once again, the all caps are kerned out significantly. Baronesse is delicate and nice smaller than it's partner. And I am a sucker for a nice silhouetted object in any layout.
