Sauchiehall Street Early 20th Century?

I went in to the Exhibition of the History of Sauchiehall Street with Smells this afternoon.
The Main photo is Sauchiehall Street going East.
The extra photo is a Horse Drawn Omnibus on the corner of Sauchiehall Street and Kelvingrove Street in the 1860's.

There was some interesting History of Sauchiehall Street. One in particular showed a Picture of an Advert for Hengler's Circus which used to be where the O2 was until recently when it was demolished.
