Abraham Lincoln is one of those figures from history that most people seem to be interested in. The Abraham Lincoln Presidential Library and Museum have a podcast based on the premise of talking about objects from their vault of Lincolnalia. It sounds like it ought to be interesting. I listened to the first one which didn't really grab me. But podcasting seems to be a skill that improves with practice so I'll try a few more before I make a judgement. No link at the moment. I don't know why, but for some reason I can't get through to their website either on the link they sent me, nor on Google nor from the iTunes store.
If you want to give it a listen, the only way that worked for me was to search for 'stories from the vault' in the iTunes store and subscribe there. (I am not in the US so the problem may well be local to me).
