If you enjoy old-time radio shows, then you're probably familiar with "The CBS Radio Mystery Theater". Fans of the show have taken it upon themselves to create a series of trading card sets for the show.
The goal is to have a total of seven series with a grand total of 56 cards. The first series will have 9 cards (including 1 checklist card).

If you're interested, here's the link to more information about the cards and the opportunity to purchase them: Radio Trading Cards

This is the first set of trading cards about which I've been excited in a VERY long time.

The cards have an interesting look - a portrait style like something from the 60's-70's. I remember Mason Adams in different things like "F/X" and he did a lot of voice work in his time.
