Here's a card from the good old days, back before George W. Bush and Willow Creek Community Church declared war on Christmas. I'm sure that many people who genuinely believe that a war is being waged against Christmas think that cards like this were the norm back in the day, but nothing could be farther from the truth. Religious cards such as this were exceeedingly rare. Sure, you'd see angels here are there, and churches, but explicitly religious scenes such as this one were hard to come by. No one really seems to know why, but my hypothesis is that people back then viewed religion as being too solemn and dignified to use on something as inherently frivolous as a Christmas card. Regardless what the reason was, the fact remains that it's far easier to find a religious Christmas card today than it would have been in the first half of the 20th Century.
