How can you tell if a doorstop is a Hubley?

To tell if a doorstop is a Hubley, look for a three-digit number printed on the back or bottom of the piece. Some doorstops will also feature the manufacturer's imprint. Items made during the 1940s may have the name "Fish" stamped on them next to a copyright symbol. This marking indicates that the doorstop was part of a line produced with the help of artist Anne Fish. If you're still uncertain about the authenticity of a piece, a certified appraiser or experienced antique dealer should be able to assist you. Find a range of Hubley doorstops on 1stDibs.
