Postcard for traveling across country...from Iowa City, Iowa to San Francisco, CA. Vintage map, Greyhound bus, and bus ticket. Found a vintage stamp. Postage in 1969 was 6 cents so I figured a 4 cent postcard would be fairly correct. I'm trying to be somewhat accurate, but not quite finished with my postcard. Still something missing. I'll keep looking, but wanted to post my progress. Thanks to Rebecca, I've remembered some events of the trip. Some pleasant, some not so. More to come.
