Great original tintype of Leander "Lee" Wilmarth (1849-1941) dressed as a clown, probably taken in or around Des Moines Iowa, where he lived in the 1870s. He later moved to Texas, San Bernardino, and finally Redlands, CA, where his house still stands. You can find more info on him on The Redlands Area Historical Society website, under Resources / Biographies.
He is not identified on this tintype but I'm 100% sure it's Lee, because at one time I had quite a few interesting photos of him that I purchased along with this tintype, and several were identified.
Tintype is about 3.5" x 2.5" and in very good antique condition.
