Thrift Is Blessing Mosaic

This mosaic is above what was a TSB (Trustee Savings Bank) on the corner of Lothian Road and Fountainbridge.  The bank seems to have been sending a message to the public although it's actually a quote from The Merchant of Venice!  Shylock gives it as part of his defence for lending money.   I was just off to meet J & D for coffee and cake so I clearly wasn't on message!
