These tiles have held up remarkably well considering it's been over 50 years. They're for the 1975 centennial, outside the building at 6th Ave & MacLeod Trail SE. It's a Bow Valley College building now but once upon a time it was the Calgary Catholic School District headquarters. I'm guessing some school children made these tiles. #Calgary #CalgaryCentennials #DowntownCalgary #yyc
