I was born in 1951 and I think there was no Visa logo in 1970 but BankAmericard. I presume this was just a test
No..no test. Founders.
What is now Visa was born in 1958 with the Bank of America. It's logo was/is blue, white and gold colors with BankAmericard on it. Ten years later, the Royal Bank of Canada, Canadian Imperial Bank, the Toronto Dominion Bank and Banque Canadienne National formed CHARGEX Ltd. through a license from BankAmeriCard. Same colors and format for the card, only CHARGEX on it.
In 1974, all the Bank of America's international licensees chartered an international company, IBANCO, to administer BankAmeriCard, Inc. outside the U.S. The card name was changed to VISA to make it palatable internationally. Its success is legendary.
Outside the removal of the bank names within the colors, the symbol has not changed. In fact, the card colors became the symbol..which is not uncommon.
