Thanks for the quick responses!
I have used the old blue paper type (has French on it) to rent a car in 2002. No problems.
Now I have used Booking.com to rent a car from Alamo and on the voucher you download it says:
"Licence
The main driver and any additional drivers will need to provide a full driving
licence in their name.
An International Driving Permit is required if the driving licence is printed with
non-Roman Alphabet.
If the driving licence is in a language other than English, an International Driver’s
Permit is required, along with the renter’s country of residence driving licence."
Booking.com might have taken that information from Alamo itself, not sure.
Google search for Alamo license requirements gave this handy website:

"Customers travelling to the U.S. and Canada from other countries:
It is important that customers check with the appropriate Department of Motor Vehicles in the States or Provinces in which they intend to travel to ensure compliance with their various licensing laws. The following practices are used to ensure the customer is presenting a facially valid license at the time of rental.
Customers traveling to the United States and Canada from another country must present the following:
Their home country driver's license, and
If the home country license is in a language other than English (or French, for rentals in Canada) and the letters are English (i.e. German, Spanish, etc.) an International Driver's Permit is recommended, but not required, for translation purposes in addition to the home country license.
If the home country license is in a language other than English and the letters are not English (i.e.alphabet is not an extended Latin-based alphabet like German or Spanish but is Russian, Japanese, Arabic, etc.) an International Driver's Permit is required.
If an International Driver's permit cannot be obtained in the home country, another professional, type-written translation may be substituted. In either case the home country license must also be presented."
