Looks like a 69. Look carefully at the serial # right on the badge right below where it says Land Yacht (that denotes a trim grade, International was the other choice back then). Here is how to decode it:
Identification Numbers for 1969 to 1980
1. Locate and write down the nine- or 10-digit serial number from the A-frame.
2. Read the digit in the first position to determine if it is an "I," indicating an International model, an "E," indicating an Excella model, or an "L," indicating a Land Yacht model. Read the digits in the second and third positions to see the length in feet. Read the digit in the fourth position to see a code for the floor plan, detailed on the Airstream publication listed in the References section.
3. Read the digit in the fifth position to identify the final digit of the model year. Read the digit in the sixth position to determine if it is an "S," indicating manufacture in California, or a "J," indicating manufacture in Jackson Center, Ohio. Read the final three digits to identify a unit built in the 1960s or four digits to identify a unit built in the 1970s.
