Nice to see that somebody else is tackling this one - I was beginning to feel a bit lonely.
Another group puzzle from 2011 was No Name 11
Ice Ice Baby (Vanilla Ice), where I sneaked in a point at the last minute thanks to Vicke the Viking.
One of the solutions linked an ice cream van of Glaces Ruiz, apparently a common sight in Cambrai in northern France, with a Blériot voiturette (Louis Blériot was born in Cambrai).
For this puzzle the link is with Street H, which is Place Aristide Briand in Cambrai. This is where the Glaces Ruiz van is usually seen, but I can't find it on Google Street View, but as the images were taken in February, maybe that's not surprising.
