Yes it was!
There was a Corona beer In Puerto Rico by the mid 50's it was
the competitor with Cerveza India another Puertorrican beer. The
company began selling beer in Puerto Rico and the United States
under its "Corona" trademark in July 1957- This means they were
officially the first ones with the Corona name at least in Puerto
Rico giving them the right for the registration and name. Even
though it was not related to Mexican product Cerveza Corona-Extra
Cerveceria Modelo, S.a. De C.v., a Mexican Corporation in which Mr.
James Stuart, Jr. was the president at time. A legal battle for
distribution of their product began by filing a petition on federal
court concerning the distribution rights of beverages in the US.
Later on LA PREFERIDA, INC. "Corona from Puerto Rico" President Mr.
Ralph Steinbarth monetarily settled after the company filed
bankruptcy under chapter 11 due to presumptive losses of apparent
pre-accord distribution agreements with Cerveceria Modelo, S.a. De
C.v for another product Malta Corona (carbonated malt beverage).
Both products Cerveza Corona and Malta Corona were created in
Puerto Rico. The Mascot for Cerveza Corona was a Puertorrican
"average guy" like cartoon called "Cantalicio". He took part of
most of the dialogues in the Corona beer from Puerto Rico ads and
TV commercials. Some of them can be seen still online on
YouTube.
