An interesting glass paperweight, produced in about the 1920s to advertise Wilson Boilers of Glasgow. William Wilson & Co produced industrial boilers from the Lilybank Boilerworks in Glasgow from 1852. This piece may have been a promotional gift given away to prospective customers. It is made of soild, thick glass with a colour image of a Wilson boiler printed to the base, backed with white enamel paint. It is in very good condition.
