Quick! Go check under your couch cushions. The moon is for sale for two cents according to this vintage postcard.
This pictured Ritchey-Chrétien telescope or RTC provided a relatively large field of view due to its primary and seconday hyperbolic mirrors. It was invented in the early 1910s by American astronomer George Willis Ritchey and the French astronomer Henri Chrétien.
Here is a little poem to get you in the vintage postcard mood.
To The Moon
Art thou pale for wea riness
Of climbing heaven and gazing on the earth,
Wandering companionless
Among the stars that have a different birth,
And ever changing, like a Joyless eye
That finds no object worth its constancy?
By Percy Shelley (I'm sure that he would have liked to collect vintage postcards too)
