Someone gave me a large collection of old matchbook covers, they all look like they're from the 50s and 60s and bring to mind an era where getting the word out to consumers meant fitting a ton of information on a matchbook. I like the 'pretty widow' matchbook because that sort of humor probably wouldn't fly today at all.
Strange how when you collect one thing, people want to give you other random things to collect. My sugar packet collection acts that way. It's like a magnet for other random collectible items. People save me pepper, salt and other random condiments... I've even inherited a napkin collection of all things. Some of them are so old, the paper is brittle.
