Saw this at Mystic Blue Signs in New Orleans last summer during TypeCon. It was in a big old French book about lettering and engraving. I wish I’d written down some information about it.
I think it was from around 1880. Heard from someone that it is from 1859.
The alphabet on this particular page was very unexpected. It looks almost like Avant Garde in some ways. And dig that crazy “g”! Way ahead of its time.
