Traditional weekly street market

I saw this sign in our local, weekly street market.
Historically, very village and town, in Spain, had at least one open air street market,.... the mercadillo.....fresh vegetables, fruits, flowers, clothes, toys, ceramic, shoes, boots, leather belts are all for sale.....
....today, in the towns, there are supermarkets, hyper markets, and huge foreign stores selling mass produced cheap goods......
This sign....is, perhaps, a call from the heart, appealing to customers to buy locally produced and locally made goods.
Progress?¿
