The company appeared in "The Guinness Book of World Records" in 1995 for the highest price for a manuscript in the United States: "On 16 December 1992, a Lincoln manuscript was sold for $1.54 million. The one page script was written in preparation for a speech. It is the first surviving formulation of his 'House Divided' doctrine, written in the winter of 1857 or 1858. The manuscript has been bought by Seth Kaller of Kaller Historical Documents" for the Gilder Lehrman Collection. Other notable acquisitions include The Emancipation Proclamation, an original copy of the Declaration of Independence, and the Vostok 3KA-2 Russian space capsule that launched the mannequin "Ivan Ivanovich", and the dog "Zvezdochka", into space 18 days prior to the first manned space expedition piloted by Yuri Gagarin.
