I have some stocks that were purchased in the early 70's. They are for Ramada inn. Is this stock still valid or is it now worthless

The Ramada chain of hotels is now part of the Wyndham group. You can contact their Investor Relations dept here:

Investor Relations | Wyndham Worldwide (http://www.wyndhamworldwide.com/investors)

Give the stock certificate #s and they can tell if you are entitled to Wyndham shares in return.
