The History Blog is a superb site that does daily posts on an interesting piece of history in the news, as chosen by "livius". Well chosen and interesting content with decent pictures. The blog is always worth a visit and is very well curated.
Recently, we have had a post about the first Christmas card created in 1843 by Sir Henry Cole, a British civil servant, organiser of the Great Exhibition at Crystal Palace in 1851 and postal reform advocate. There were 1000 cards made and some were also sent to America. However, as the post says, the "American bourgeois sensibilities" were not so happy with the depiction of the whole family enjoying a Christmas drink, including the toddler. A bit different today.

A more recent post is about some famous Minoan frescos on the island of Thera. Dating from the 17th Century BC, the colourful pictures show monkeys playing and hanging around. They have now been identified as grey langurs, a species native to southern Asia e.g. the Indus Valley. As the comments mention though, it is a little surprising no one tried to identify them before. In addition, no one should be surprised at how much long distant trade occurred in the bronze age. It is an open and interesting question on why most of it stopped.
