This 1950 ad for Zippo lighters has a wonderful Santa comic in it. Hooray! The new one's out!
You may buy a Zippo just to keep around, for those occasions when you need to make a fire, expecting the Zippo to be very reliable. It is reliable, so long as you use it every day and keep it filled. The reservoir in a Zippo isn't sealed in any real way. The two halves of a zippo slide together, and inside is a dense square of cotton, which keeps the fuel from sloshing around or running out. What this design doesn't do is keep it from evaporating away in a week or two. So, unless you're "on the junk" look elsewhere for your occasional firemaker.
Anyhoo, on to the comic!
