The designers of these labels and poster stamps probably each did 100s of them in the course of their careers, but it's sad that most have ended up in the dustbin of obscurity and will never receive due credit for their artwork. At least their designs have a legacy and it makes me happy to share them. I've credited the owners in each case.
