The Original Old-Time Radio BBS

Hi all -
I am currently involved with a production of It's A Wonderful Life, The Radio Show and I am looking for period radio show posters of old time radio shows from 1940's (or pre 1940's).

I am having no luck so far finding anything.

Any help anyone can provide would be greatly appreciated.

Thanks

if you have any information or links that might be of help.

Two or three years ago I saw at least one (maybe two) posters on eBay for the new CBS radio line-up of January, 1949. I don't know where you'd fine something like that today.

I could be wrong, but most radio ads I've seen have tie-ins with their sponsors.
