Abraham Lincoln was one of H.T. Webster‘s personal heroes, and today would have been his 215th birthday. Whenever an appropriate weekday series was scheduled for February 12th, Webster occasionally took the opportunity to draw a birthday tribute. This example (taken from “The Best of H.T. Webster“, page 253) originally appeared in 1919 (on what would have been Lincoln’s 110th birthday):
This video from the Smithsonian Magazine shows a couple of alternate designs that were proposed for the Lincoln Memorial, along with five surprising facts:
1) Lincoln was an accomplished wrestler; and …
2) … is the only President to hold a patent for his own invention;
3) … stored papers in his top hat;
4) … attended seances in the White House; and
5) … established the Secret Service.
Comics I Don't Understand 
I’m very surprised to realize I knew 1, 2, and 5 of those facts.
Note for mods, I made a comment that was supposed to be here. The comment went to moderation, so if you see this hopefully everything can be done at once.
@ Brian (2) – Rescuing your comment from the moderation queue is simple to do (or at least it would be, if the idiots at wordpress would stop tweaking their software), but moving it to a different thread is not. (You can manually copy/paste it to here from the other thread if you still want to.)
P.S. Back during Comicgeddon, there was a short discussion about whether it would be worth an attempt to rescue the former CIDU comment archive (portions of it are still available from the Wayback Machine). Bill was not aware of any method that would permit a wholesale import, and since it would have been prohibitively laborious to import them all one comment at a time, he was forced to restart CIDU from the beginning.
While if someone had asked if Lincoln was involved in any sports I would probably not have remembered – but seeing it written out – in the back of my head (where all the cobwebs and old file storage is) that I knew he was a wrestler when he was young from some story in a book read while in school.
Similarly that he stored papers in his hat and that he went to seances in the White House set up by his wife (I believe related to the death of one of their sons?) both ring a bell. Also that the Secret Service was established under him to deal with counterfeiting. (We accountants know much about money.)
