I have contended for years that the 'goods' in the flea markets and garage sales is continuously recycled... these people buy 'crap' at the sales and markets and then sell it in their booths or garage sales. I believe that nothing new is added.. it is all just moving from booth to booth .. garage to garage..
Hmmm, maybe that why all the oldest stuff is cast iron and dented up stainless steel??? ;O)
