You might not be getting the gist of the comments offered? That sign was never produced for, or used by the Texaco company, therefore it is termed "not original".
If you are looking for "that exact modern sign", I suggest you contact the seller on ebay and see if he will sell you one with or without the neon!
This site is mostly used by collectors of "old, original to the gas & oil industry of the past" and the signs and memorabilia associated with it.
The sign you are looking for is a new, modern, decorator piece and the collectors that inhabit these pages, do not mess around with that stuff for the most part.
