    This blog is a collection of the interesting, the weird, and sometimes the need-to-know about history, culled from around the internet. It has pictures, it has quotes, it occasionally has my own opinions on things. If you want to know more about anything posted, follow the link at the "source" on the bottom of each post. And if you really like my work, buy me a coffee or become a patron!
