SPRINGFIELD, Ill. (AP) — The Abraham Lincoln Presidential Library and Museum is marking the 150th anniversary of the end of slavery. The Springfield museum is displaying a copy of the 13th Amendment signed by Lincoln beginning Sunday. That’s the anniversary of the ratification of the amendment ending slavery. The museum also will show a video about the amendment’s impact and offer free admission to an exhibit about the Steven Spielberg film “Lincoln.” The Lincoln Presidential Library copy of the amendment is considered rare and fragile. It’s signed by more than 100 lawmakers who voted for it, in addition to Lincoln. It will be on display through Dec. 28.
