THE JUNK MARKET
I own a market stand. It is made of steel bars that can be fit together up to 3 meters lenght and about 2,20 meters high.
The best places for selling the most semi-antiques that can be found at the garbage refuse removal are the junk markets on festival grounds or in the old parts of towns.
I use to deal within a radius of about 130 kilometres.
For common crap, a junk market on the parking lot of a supermarket is sufficient enough. You don't even need to fit the market stand. Just open the trunk and sell.
