DOC - it shouldn't even take a seasoned collector. Anybody looking to spend this kind of money shoud have taken some time to learn a bit about porcelain signage.
And if you look, the 'Walker' logo is obviously hand-painted - and with the additional lettering of the sign company the made this sign added to the 'logo'. See the 2nd photo in the listing.
The sellers of this particular sign are telling you everything you need to know about it. It is a reproduction, painted sign ready to be mounted to a can and already drilled for neon.
No one - I repeat, no one that is running this auction is trying to deceive anybody. And with the hand-painted logo (under the clear coat), it shouldn't be a problem 'on down the line'.
Buyers need to take some responsibility for their purchases by educating themselves BEFORE they go shopping.
