Thank you for submitting your item for appraisal. This appears to be a set of three mirrors in a western japonism style, manufactured by or for "reliable MFG co." in Union, New Jersey which also sold a line of "op art" mirrors under the brand name " a Sharon Art concept" in the late 1960s. The inscription imitates chinese characters, so does the round seal. The "characters" are purely decorative, there is no meaning to it. The estimate is based on similar offered or sold at auction.
