First Comic and The Search Starts

It all started when my Dad gave me this comic book he bought at San Diego ComiCon last year. And now I am on the quest for comic books featuring our dear 16th president. Abraham Lincoln has been dear to me ever since I saw this video. If you can, please help me in my search. I don't know how many (if any) comic books there are out there with Mr. Lincoln but I'm willing to look. :D
