I came across this at an estate sale. Price? $9.99. I thought it was just an old Barbie item, (always promising) but was especially drawn to the cool graphic. At $9.99, I thought perhaps the guy running the sale had checked it out on eBay and knew its value. But I bought it anyway. Well, I came home to find out that 1959 was the year on the box and THE FIRST YEAR FOR BARBIE!! I started watching other auctions and this box seemed to go for $70ish. Then I noticed mine had Barbie tm instead of Barbie r. Mine was from the first part of the first year, and my box has a sticker that says "brunette" on it. Brunette dolls were sold once for every three blonde dolls. It's on auction now.
I did have a mishap on eBay with listing this the first time. (and deservedly earned my first negative feedback....) but that's another story.
