I uploaded a partial scan of a 1948 Philco brochure.
It's a promo piece pushing Television as the best way to watch Football.
I didn't scan all of it because it's mostly scores from 1947 with a place to enter scores from the 1948 season.
There is a short article about how to watch Football on TV or listen to it on Radio but that's not included in this PDF, maybe at a later date I'll add that.
The address of the shop it came from is stamped on the front and I've included a Google image of the building now (a Meat Market) can't you just imagine that store front with the new Philco line from 1948 in the windows!
Here's a link.
