I have 3 items relating to the subject here, so starting first with the photos above.
These are some of the greenie poles aroond the backies in Kemnay Gardens where we lived. They were standard council installations that everyone in Craigie had in the 60's. However, none of the ones in the snaps exist anymore. All the garden areas have been partitioned off from each other and everyone uses whirligigs now.
With old style tenements, many had pulley systems outside the windows on the upper floors which were attached to a large main pole that held many clothes lines.
Which brings me to the 2nd item. Some examples of these pulleys crop up in a short film I have (below), the footage of which was taken around various locations in Dundee in the 60's.
But before we go on a retro tour of the backies, item 3 is a wee reminder of how washing powder was advertised on tv in the 60's, with the one below being for Fairy Snow, who's slogan some of you may recall... "Forces Grey Out - Forces White In!"
