JUSTUS BECKER, Germany’s famous street artist, has brightened up a newly renovated Green P parking garage, just off Yonge Street. It’s hard to miss. The painting will be the first between Frankfurt and Toronto muralsts.This Mural Exchange Project celebrates the 30-year relationship between the two cities, whose landscapes appear in the reflected glasses (Frankfurt on the left; Toronto on the right).  A TORONTO street artist will collaborate by painting a mural in Frankfurt with a similar theme.
