Chess Mardi Gras

Today being Mardi Gras, and me having no concrete ideas and little time for a more profound post, let's just celebrate the day. Seen on eBay: 'Chess sports carnival parade car in France original 1950s photo postcard'.

The description added only,

Size: approx. 3.5" x 5.5" ( 9 x 14 cm).

The back of the card said,

Carnaval de Nice
Le Nain Jaune
Const: J-B. Pissarello

That's Nice, France, where Le Nain Jaune means 'The Yellow Dwarf'. As for 'Const', I'm not sure what it means -- maybe 'constructeur' of the float? For another take on the same topic, see Chess Carnaval (March 2012).
