Antique catalog/magazine question...?

Question

I have some old catalogs/magazines that I have no idea of their value:

-"Penn Automatic Controls" from Penn Electric Switch Co. in Goshen, Indiana. It is from February 1942. Cover is all black with "Penn" in a red circle, and "Automatic Controls" in a red rectangle

-And "Official Directory and Log: 21st Annual World's Premiere Air Classic" "National Air Races, Cleveland Ohio" From 1947. Cover is silver with two airplanes flying on the front with a red and white checkered tower in the background. There is a blue circle in the upper left front of the magazine with "50 cents" printed on it.

I picked these up at a yard sale because I thought they might be worth something...

Answer 1

Check out eBay and see what similar ones are going for. Also their value depends on their condition.
