Puerto Rico was referred to as Porto Rico from 1898 to 1932.

I guess all chips were sent to "Porto Rico" if sent before 1932. I have 5 different PR crest and seals from USPC on my site. All chips were delivered prior to 1932.

Maybe I should rename my CPR Casino de Porto Rico although Porto was only used by the US. I guess in Puerto Rico the name used was Puerto and not Porto. I'll leave it Puerto
