I don't know, but here is a better image of it and maybe someone will recognise it.

For their inspiration on this project, the artists turned to the History of the Gorbals. The Gorbals grew up as a satellite of Glasgow. It was famous as the first staging post for immigrants; first there were the Highlanders from the Clearances, then the Irish from the Potato Famine and then the Jews from Eastern Europe. This was a place that thrived on cultural diversity: In a treatise on Scotland in the 19th Century, Scots were advised to visit the Gorbals to “experience the sounds and smells of Europe”.
As described above the Gorbals was always a place of arrival, yet also a place to reach out from. Most immigrants would aim to find their feet in the Gorbals and the move to the new world beyond. It was this sense of reaching out that became a focus to be embodied within the commission to create a gateway to the Gorbals, that is, The Gatekeeper.
The Gatekeeper depicts a dream. The figure in the photograph seems to emerge from the past and dreams herself as the sculpted figure above. The sculpted figure hangs in the air free and unencumbered; she is a dream of the future.
so now you know!
