Flea markets are open air markets selling second hand and often cheap goods. In Australia we call them trash and treasure, in the UK they are known as car boot sales in France and French speaking Canada they are known as Marché aux puces.
Where did the term come from? Quoting from Albert LaFarge 1998 article in an edition of 'Todays Flea Market' magazine, he says: "There is a general agreement that the term "Flea Market" is a literal translation of the French marche aux puces, an outdoor bazaar in Paris, France, named after those pesky little parasites of the order Siphonaptera (or "wingless bloodsucker") that infested the upholstery of old furniture brought out for sale."
I didn't buy clothes at the market this time...but I did buy this! A little worse for wear (hmm, puces?) but a lovely block print circa 1964 - a very good year!
