Two postcards -
Upper one mailed from DeVRy May 12, 1965.
Bottom: Radio and Television Institute return card, date unknown;
Guessing 1930's, as it appears to show a mechanical TV flying spot scanner.

That's Dr. Ray Kell and Dr. Ernst Alexanderson in the mechanical picture. Here is another one of them together in front of a later version of the television projector.

I guess since this was a home-training offer, they felt free to use any photos of TV and radio gear.

St. Anthony Court is a non-existent street name in Chicago today.

Edit: according to a document at the Chicago Historical Society web site, St. Anthony Ct. was renamed Hamilton Avenue. The original designation of Court corresponds to the short length of this segment of Hamilton Ave, two blocks. The name seems to have been extended from the nearest north-south street, Hamilton Ave, which is offset to the east, south of 4800. Google Earth streetview shows 4806 N Hamilton Ave to be a modern condominium type building.

Several years ago I acquired many items from N.R.I. (National Radio Institute). A now deceased local TV repairman's life was put to the curb upon his death by his wife. Lucky for guys like some of us I guess, but I thought in a way that it was sad. Likely all of this junk probably fed and clothed the person who set it all to the garbage man, or in this case a friend of mine.

At any rate, there is a ton of great information in the many leather bound instruction books from the late 40s and into the 50s. I even had the home build O-scope and V.O.M. originally, but someone out in California jumped right on that stuff quick, fast, and in a hurry. I figure it went to some museum, but I didn't bother asking too many questions.
