This art is located in Ruthven Lane, just off from Byres Road, and is a porthole into a good many, smaller shops and organisations.
Am not sure, but this signature looks like its “Dan Leo” and have searched for him to see if he has other work to his name.
He appears to be not only highly talented, but also to specialise in large, street murals – well done!
