Looking for early examples of type designed for materials other than paper.

Hello!

I'm looking for specimens and/or early in-use examples of typefaces designed specifically for use on alternative materials (e.g. debossed in leather, punched into license plates, stenciled on cardboard shippers, etc.). I'm curious to look into the design decisions that went into solving problems associated with these uncommon applications. Any resources come to mind off the top of your head?

Thanks in advance,
Ryan
