A couple of weeks ago, we were discussing pop tops, and someone referenced a National Geographics issue with a chart showing different pop top (or pull tab) styles found on different beverage cans.

One list member e-mailed me that he was having trouble finding a copy. so I scanned in the chart in .jpg format.  If anyone wants the scan, e-mail me off list, and I will e-mail a copy to you.
