A Hopkins Porta-portal (circa 1950) one of dozens of unobtrusive, moveable portals constructed by Alberta Hopkins, who had a rather irritating husband. The portals quickly became immensely popular amongst those with unbearable spouses, neighbours, pets and children, and were produced up until the late 60s when television became widespread, providing an alternate form of escapism. Many Porta-portals still exist in working order today, and care should always be taken when entering unobtrusive, portable looking spaces for the first time.
