Thanks

This blog would not have been possible without the support of the following people and organisations:

• The authors of the outstanding blogs Invisible Paris and Invisible Bordeaux for blazing the invisible trail and helping me set up this blog

• The Fondation Berliet, (39 Avenue Esquirol, 69003 Lyon) for access to their archive and permission to reproduce the photographs used in the post on the Rue Feuillat factory

• The street art collective Birdy Kids, who not only graciously agreed to let me interview them, but also provided photos for my article

• The Lyon municipal archives, for pointing me in the right direction in my search for the answers to the mystery surrounding the Hôtel Payen
