ot many of Keckley's designs still exist actually. And even with those pieces that do exist, there’s a question as to whether they can be attributed to Keckley. The Smithsonian’s National Museum of American History has a Mary Lincoln gown, a purple velvet dress with two bodices, that the first lady wore during the second presidential inauguration. There’s a buffalo plaid green and white day dress with a cape at the Chicago History Museum. At the Abraham Lincoln Presidential Library and Museum in Illinois, you’ll find a black silk dress with a strawberry motif that you’d wear to a strawberry party, which was a 19th-century Midwestern picnic tradition, but it’s disputed as to whether or not it’s a Keckley.
