Alright, Which one of you guys owns a sign company and is having a little too much time on your hands making these “Vintage Porcelain Signs”?
 

I wonder if they’re porcelain, or really enamel, but one should never underestimate the ability of the Chinese to produce reasonably good quality at ridiculously low cost.  (I know a dealer who imports fake “antique” furniture, & I’m amazed by how well they’ve learned to do the fakery, if they’re provided with models to copy.)  Anyway, tin repros have been around since the ’70s, so many of them are beginning to look “vintage.”  ALL tin signs, by the way, should be suspect, because the vast majority of late 19th & early 20th C. advertising signs were printed on cardboard or paper.  What’s more problematic, if you’re a print collector, are repro paper prints & posters, because they began appearing in the ’60s, & many have by now, depending on how they’ve been stored, acquired signs of legit aging.
