Air bag helmet demo

An air bag bicycle helmet has been in the news lately, and there is an evaluation of it online, if you care for the details. However, years ago, Sheldon posted a scan of a poster for another air bag helmet on the site. Unfortunately, he had only a rather worn copy to scan from. We’ve now had the loan of a copy in fine condition and had it professionally scanned. A small copy of it is below but you may view it in its full glory elsewhere on the site.
