This reminded me of the Pasadena City College flea market. You will find the following here:
Vintage postcards
LP's
Old lamps, tea cups, rugs, books
Artwork
Some clothing ( I bought two vintage silk scarves from here).
Small furniture
Vintage kitchen items
Knick knacks like owl salt and pepper shakers
Everything is reasonably priced.
They are willing to bargain, make sure you say "Bonjour" first! Don't be rude, or they will be rude back. I noticed another American getting the cold shoulder when she just rambled in English, expecting the merchant to know English. A Bonjour will go a long way, even if you don't know anymore French ( Merci, Sil vois plait, Au revoir will help you get by as well).
Have fun treasure hunting in the City of Light. Oh, and get there early, around 8 am, to get the good finds.
