We are offering this unique Pepsi bottle cap porcelain sign.    Please look carefully at the photos - this sign is very unique as it does not have the ridges all the way around it - it is smooth on the top portion of the sign.  Also, under the Pepsi Cola logo, there is a "star" symbol which I have not seen on other signs.   If anyone Pepsi collectors can provide any insight into this I would appreciate it as I have tried to research but am unable to come up with any information.   The sign is definitely an older porcelain sign - does not appear to be a reproduction.    There is no makers mark on the sign.   I am wondering if it may be a Pepsi sign from another country.   It has a diameter of about 18.5".
