Following a rally in Battle Creek last month, President Donald Trump took the time to sign autographs for supporters in the audience. One of those autographs ended up on a copy of the Articles of Impeachment against the president and that document will now be auctioned off later this month.

According to TMZ, the auction will be conducted by Goldin Auction starting Jan. 20 and running until Feb. 22. The opening bid on the item is for $4,000 and the expectation is that it end up selling for between $50,000 - $100,000.

The signature appears to be authentic and is scribbled on the title page of the document. The Articles of Impeachment were issued the day prior to the Battle Creek rally which was held on Dec. 18. For more information on how to bid on the item visit the auction website.
