Vintage handcrafted wood wall clock with signature certificate

The maker of this 1993 timepiece is Steven Mackintosh, a custom woodworker and clockmaker. It evokes a period style of between 1925–1940. According to the attached documentation on the back, Mackintosh salvaged an original, eccentric square-faced clock from a recently closed candy and peanut butter factory boiler room in Oswego, New York. Inspired by its unusual graphic numbers, he modernized the internal joinery and casing out of his woodworking shop, replicating the original graphics with the help of his sister, Jane Mackintosh.
