You didn't upload the picture, but the original OGD image (the laughing, happy drinking grand dad) began being phased out in the late '50s. I've seen a bust displayed along with the old image in a 1959 ad, and I believe they continued that for the next couple of years. The guess of 1960 to 1963, based on the bottle markings is not always accurate, but looks to be right on the money here. If you buy a bottle of OGD today (86 or 100 proof as appropriate) and then taste them side by side you will immediately understand what so few others here can... which is just how different even everyday bourbon was before the '80s than they are today.
