Each mirror is 2-1/8”. The only ones with some significant silvering issues are the first with 10% covered by a white blotch and the fifth which is missing a large rectangle of silvering with about 60% remaining intact. The first five mirrors are from a single series and are titled as: "Cascade-Hall & Gardens, Missouri State Bld’g, Palace Of Varied Industries, Palace Of Liberal Arts, Palace Of Transportation." Only the Liberal Arts example shows a tiny bit of staining on extreme edge and the cello surface is just a hair concave. The other four are NM. The next group of three pictures: Manufacturer’s Building, Transportation Building, Varied Industries Building. The first two have some tiny age dots around the extreme perimeters but the illustrated areas remain clean and the third item in the group is totally clean although with just a tiny ripple mark at the center showing in reflected light. A very nice group of seldom seen 1904 pocket mirrors.
