Fifteen issues from Switzerland, France, Germany, the United States, Canada, Italy, Sweden/Norway, Australia, Argentina, the Netherlands/Belgium/Luxembourg, Thailand/Malaysia/Singapore, Czech Republic/Slovakia, Greece, Turkey, and the United Kingdom, dated December 5, 2007. They are not sealed, but I believe they have only been viewed once. I prefer to sell them as a set, but if you would like to purchase them individually, please let me know in the comments.
