The bottom pic is how I remember Ibrox as a kid. I went to the primary school on the left of the pic and used to watch the players arriving for training from the playground. There were no Aston Martins then, the Edinburgh players like Millar, Brand and a young John Greig would arrive by subway and turn the corner from Copland rd where the pram is pictured. There was no access to Ibrox from Mafeking St then. The tenement pictured collapsed and/or was demolished due to subsidence in the late sixties/early seventies. You can still see the new gable end today and where the building was pinned.
Great post OP.
