carboot sales are just that-people gather together,paying a set fee to sell whatever they bring with them in the back of their car,and then people...well,buy it XD They're becoming more like markets where I live now though-the fees are getting too much for regular car boot sellers to sell,in favour of attempting to deter the regular 'traders' and counterfeit sellers from selling there :\ theres less and less carbooters every year,which is sad.
anyway,great find! I wish my pony finds were that good,but unfortunately(or fortunately depending how you look at it lol) theres another collector in my area who goes to the same bootsales,and always seems to get up earlier than me >> I need to set my alarm for 6am or something XD
