N.T.C Public telephone sign 5x3 on EBay item #262985024285 -Repro?

Hi Friends,
I judged the attached current Ebay listing as a 1970s era reproduction. The revere stamp is seen on other reproduction signs sold on ETSY.
Anyone care to comment?

Most likely fake but NTC was in England. National Telephone Company.Later nationalised by the GPO

The postal codes on the makers address appear to be modern modern, I do not know how long the NTC used that logo but I would assume it is a reproduction or fantasy piece

I have a different sign made by the same company.
