Museum of History

The Museum of History is a former museum located in Washington D.C. in Fallout 3. The structure itself is relatively undamaged, but the exhibits have mostly been destroyed or ruined. It contains the entrance to the Underworld, which is a city of sentient ghouls. Among other Lincoln artifacts (see below) the Museum also houses the only Lincoln's Repeater and Lincoln's Hat in the game.

The museum is infested by feral ghouls.

Lincoln's Artifacts
The Museum of History houses a considerable number of artifacts of Abraham Lincoln. As the former president is a symbol of hope for slaves in the Wastelands, his artifacts are highly sought after by both slaves and slavers (and historians, of course).

You can either keep all the items or sell them to:
 * Hannibal Hamlin from Temple of the Union (for the most caps by passing a Speech check)
 * Leroy Walker at the Lincoln Memorial
 * Abraham Washington in Rivet City

The items are:
 * Lincoln's Diary is found when you first go up the steps in the large display room on the way to the Museum of History Offices, laying on the first display to the right
 * Antique Lincoln Coin Collection is found on a bookshelf in a room on the right side of the 2nd floor of the Museum of History Offices.
 * Lincoln's Hat is found in a room on the 1st floor of the Museum of History Offices. The room is the first door to the right from the entry stairwell and has a collapsed ceiling (you can also drop down into it from the second floor).  The hat is on the floor among the rubble, next to a desk.
 * Lincoln's Repeater is in a display case on the top floor of the Museum of History Offices.
 * Civil War Draft Poster can be found in the southeast corner of the museum on the lower office level, on the floor next near the bookcases.
 * Action Abe Action Figure is in the Museum of History Offices, behind the locked door to the Archive room on a desk near the turret terminal.
 * John Wilkes Booth Wanted Poster is in the Southwest corner of the Museum of History offices on a bookshelf.
 * Lincoln Memorial Poster appears on the wall above a desk just at the top of the stairs to the 2nd floor of the Museum of History Offices (only if you have started the Head of State quest).

If you feel like you rather keep the artifacts you could just place them in your house by dropping them from the inventory and placing them wherever you like.

Other Notable Loot

 * Nikola Tesla and You on the floor of a stall in the women's restroom, just to the left of the main entrance.
 * Chinese Army: Special Ops Training Manual on the desk next to the case containing the Lincoln Repeater (second floor of museum offices).
 * D.C. Journal of Internal Medicine in the kitchen area on lower floor of the basement of the Museum (on way to Museum offices).
