Here are some ideas to work with maybe. You can design your own in just about any software these days and have it printed and mounted on foam core at your local copy center, including Office Depot type store. Large posters that are heavy on pictures and less on the specs seem to get more attention. I tried both and then one I put together of pictures taken since 1976 always gets more attention. The wife just posted scenes and pictures of hers (the Action Bronco) in various movies, catalogs, and book covers. The movie connection draws the women like crazy. People like to think they are looking at something unusual, so just try to be creative.
The other option is hand-out cards like the ones below. 4x6 cards with pictures front and spec on the back are really popular. Can be printed at any copy center. Simple sales-pitch type text seems to make them happy..
