Early 1900s Santa Christmas Greeting Card with Sleeping Children

The two children staring directly back at Santa with wide-open eyes are the detail that unravels everything: Santa—full red suit, black boots, gold buttons, and oversized gift sack included—has apparently chosen to announce his presence by dramatically sweeping open a curtain and staring directly at two children who are decidedly not asleep. The kids are clearly awake, eyes open, watching this large man in full winter gear lurk into their bedroom. The card insists the whole thing happens 'while you are asleep,' but their expressions suggest they're experiencing something closer to a home invasion than a magical surprise. Either Santa has never actually met children, or whoever designed this card wasn't paying close attention to the scene they were depicting.
