This tire ashtray has the original matching tire and glass insert. The glass is lite green. It looks like it may fluoresce under black light, but I have not tested that. On the glass it reads 'the general tire', above a shield design, and 'goes a long way to make friends' below the shield. The hard rubber tire says 'General dual balloon the blowout proof tire'. This is a harder to find tire ashtray and is in excellent condition.
