That's a really nice photo, and not one in the usual canon of Mercury-Atlas photos. Not knowing your level of classic space knowledge, I'll mention that's the type that carried the first American into orbit. I looked up the booster number, 67 D (D because it was an Atlas D, the version used for all the mercury flights), and it's Flight Mercury-Atlas 2, launched Feb. 21, 1961, which didn't carry an astronaut and wasn't even intended to go into orbit. John Glen didn't fly until Mercury-Atlas 6, exactly a year later. So that postcard was presumably published in anticipation of his flight.
Before the internet, postcards like that were one of the best sources of color space photos.
