First this leatherbound notebook dated 1919 containing the field notes of an Electrical Engineer / Electrician. The author had an engineer's perfect handwriting and he illustrated the notebook with precise and intricate color-coded diagrams covering radio, fire and burglar alarms, the properties of batteries and much more. It looks like he was compiling this with an intent to publish given his preface:
In view of the fact that most books on electricity contain much elementary and theoretical explanation unnecessary to the journeyman in the trade, I am endeavering [sis] herewith to compile useful data and drawings, giving the same as simply as possible, making this a handy reference book. -- Carl Weimer Schwarz, July 1919but I wasn't able to find anything more about him. Here's a few images:

Along the same lines this fascinating poster from "United Plumbers Supply Company, Inc, New York City" which is a full graphic "Interpretation of the Plumbing and Drainage Code of the City of New York, Copyright B. Hoffman, Domestic Sanitary Engineer, NYC".
I don't see a date but it's c1950-60.
Basically it shows all of the possible variations in NY Plumbing in one apartment building cutaway.
I love looking through Edward Tufte's Envisioning Information and this poster belongs in there. Because of its size and delicacy I wasn't able to get a decent shot of the whole thing but here's a section.
Lastly this 1950s-era binder from National Telefilm Associates called "Rocket 86" which is a collection of the pressbooks of 86 films from the 30s and 40s packaged for television. It contains classic film noir (Laura, The Dark Corner), horror (Chamber of Horrors, The Human Monster), westerns (Riders of the Purple Sage, My Darling Clementine), etc together with the ads and promo spots that were suggested for TV and newspaper use.
This is an interesting archive of early television and film history and probably layed-out the way many cineastes originally encountered these films during their television broadcast.
