Brass Shaving Mirror Portrait Of Lincoln

I highly suspect that this is definitely a one of a kind folk art piece here This shaving mirror is just so interesting. It has a wooden base, oak or walnut & the stand is made of all brass fittings .There is a eagle finial flanking each side of the mirror on top .The framed beveled mirror turns completely upside down to reveal a picture of Abe Lincoln .I simply cannot tell what the medium of the picture is of Abe, it looks like it could possibly be stamped celluloid or perhaps a charcoal on paper? The frame is an attached double frame that is wood & gesso with a faux finish to look like ivory. The frame has a small chip out of the lower corner & can be easily repaired. The mirror is the original beveled mirror & has considerable age wear, but still presents well..Im pretty certain that this shaving stand dates from about the 1870’-1880’s.In good condition overall & measuring 17” L x 8” W Base & 21” high overall.
