Single page approx. 15 x 21. These ads have been stored flat in dry storage for approx. 40 years. I originally purchased them from an automotive museum curator, these were extras that they were not going to use in the museum at that time. 
Newspapers do not age well due to the quick deterioration of pulp newsprint. To find these full page COLOR ads is rare and to find them in this condition even rarer - consequently they are expensive. To coin a term - "where are you going to find another one?"
All are in reasonable good condition but may have some light staining or rough edges. These ads will be shipped flat 
If you have any questions please feel free to contact me. Thank You for your interest, I appreciate your business!
