HI there,
I saw this item on ebay a couple of days ago, and was wondering whether it's a reproduction being passed off as an original:
https://www.ebay.com/itm/FIRESTONE-...-PORCELAIN-COLLECTIBLES-OLD/333068157819

It's got some telltale signs pointing in the direction of a fake: comes from India, rusty residue is more of an orange colour, colours are very bright, back doesn't look quite right. I'm interested because a guy I know has this exact sign and that looks a bit different; I'd say his looks more like an original, but then again, I'm a bit of a noob. (pictures of my friend's sign attached). What really puzzled me is that they're both signed by the maker Clyde (Ohio).
