As a collector I spend a lot of time searching for the smurf I need to inhance my collection, The problem I run into a lot, is the sellers don't inform you as to all the markings on the item, This is very important, to a collector as it will determine whether or not he buys and how much he is willing to pay,,,,,, SO please remember, Inform your Collectors, Tell them all information that can be found on the smurf , Look closely  ,you may even need a magnifying glass , Describe as closely as possible , the condition of the smurf, paint rubs , cleanliness , etc.  It may make a big difference,,,,,,,Thanks, biker-pete.
