Madison,
Take these India signs, add your own "story" of how you found it in a barn, take it to a local auction/fleamarket and boom you pollute the original sign market (and devalue your originals) with unmarked, very original looking fakes.
Others see the market for aged fake signs, join in and bring more fakes. Then it becomes a struggle to convince people of the aunthenicity and VALUE of your genuine originals. Along with duping the unsuspecting public.
Had I not known of this website and the flurry of fake India signs, I might have bought one myself, paid good money, and would be really PO'd to find out mines a fake
Its a problem there too in India for the same reasons.
And as the repros that were bought as repros now get older and age/wear/chip themselves, we run into this problem again.
"Grandpa had this sign in his shop for 20 years" will actually be true but with a new but now 20 yr old sign.
