Paris has its Clignancourt, then Lisboa has Feira da Ladra.
this twice-a-week flea market has as various things as old pictures, clothes, to dishes. besides outside vendor, there are also some shops in the area. At one of them, Amor de Toquio, featuring Japanese "kawaii" (cute) and vintage fashion items, I found a PanAm bag for 15 euros. I have been looking for it!
how much are those things at market worth to you, junk or treasure? find your own "eureka"s!
