That sign is a fake.
Fonts are funky and not asymmetric or proportioned in size in relation to the other letters. Why would the sign be made 46 3/4"x7 3/4"? Tin signs lose height and width to the embossing and edges being folded over, but the steel blank starts out as whole numbers.
Unusual size to be cut, makes no sense. How many 48" signs do you have that are only 8" wide. Why is the white border so narrow. Not an attractive looking sign due to the lack of width? Any company paying for marketing and advertising would have considered the dimensions and overall visual appearance with a bit more scrutiny.
Consider the source...Argentina, seller with private feedback. The sign is a fake.
