1972 O'Day Mariner Advertisement
This ad featuring #2253 is from an unknown magazine, but the date is early 1972 as they mention 2,250 boats have been built.
An Alberg Typhoon is on the opposite page - you can see it very faintly as it bleeds through a bit.
The O'Day Company certainly got a lot of mileage out of this particular picture as it was used in many of their advertisements!
