Cinema advertising slides flashed up on the screen for only a few seconds before the projector heat forced them to be changed. Many local businesses took out advertising with the cinemas and MAVtech has a large collection of local slides. Some, like this one, seem a bit unsettling today!
Most of the Foxton businesses who took out these ads were just down the road from the town's cinemas- so ads like this one would have encouraged people to do some shopping on the way home or (for later screenings) next time they were in town.
This Kete link shows the Co-Op Butchery in Main Street in 1950, across from the Clyde Street intersection. An early 'Co-Operative Butchery' was in existence as early as 1889 on Main Street, managed by John W Walsh (who later became a butchery owner)
