This is a really interesting documentary image I spotted on the web which provides a rare look at early street photography studio set ups. The backdrop being used is of an early bi-plane. It is in two sections, the customer poses behind the front section and the rest of the plane is on the backdrop. When photographed square on, the illusion is complete!
The gent with the beret is taking the photograph, and you can see a couple more props in the space, including one of those head in a hold boards. Although open to the daylight, there are also three large lamps directing light at the subject.
It is obviously French, but I do not know when (probably 1920s) or where it was taken, or by who. The Rapid Photo sign at the top suggests the stand is bigger, so perhaps the darkroom facilities are next to the studio. The sign inside says “instances” which suggests the print was processed while customers waited, although there looks to be a little brasserie behind the stand for a drink while doing so! There are a few comic seaside images on the site.
