In each and every city lies an untold number of hidden treasures. From time to time they resurface and shine once again. These tags are probably about 20 years old (I’m on the case!!) and maybe haven’t been seen for a good part of that time. The metro station is having some work done and soon the tags will disappear again. Hopefully they’ll come up for air once again in the not so distant future….2020…2025????
