This is the logo from my grandfather’s hard hat. It has to be at least 50 years old (the hat at least, a quick search for the company yielded no results). He wasn’t a construction worker by trade, but did surveying for the Ohio turnpike as a summer job when he wasn’t teaching.

I love the typeface for the “hardtop” text. A nice slab serif — a little wide, a little thin, not too bold, but with enough presence. And that “R” is perfection. If I can find some time, I’ll have to re-create the font from this photo.
