This handpainted lithograph, printed in New York, purports to be "taken from the original copy of which the plate was destroyed by an Act passed in 1848 making it sedition to publish it." It provides a list of important events in Irish history between 1167 and Dermot MacMurrough's various shenanigans and 1844 with Daniel O'Connell's sentencing to 12 months prison. To the left of the history tree there's Daniel O'Connell hanging out with Erin and her dog. To the right of the tree I'm unsure who the characters are, if anyone has any ideas or for that matter can identify the buildings in the background please comment. You can download a huge TIFF file here if you'd like to take a closer look at this image but be warned, it's about 200mb.
