Some pictures of this 1966 which gathers two complications which are very useful together: The Annual Calendar ( even if a perpetual calendar would have been better... ) and the Equation of Time.
Indeed, it is quite great to have an Equation of Time associated to a calendar you don't have to set every month, but only once in a year.
Is the Equation of Time very useful? Certainly not for the majority of us, but this kind of complications makes me dream.

And I am not the only one to like it...
Best,
