Vivian, I sell sculptures also, and sold many on ebay to different countries. Shipping is a big deal, can be very expensive and risky depending on where and how you ship. The smaller items I use U.S postal service, The larger one UPS or Fed Ex depends where your shipping again. I get my rates on line from the website of the shipping service, there you can use there calculators to determine size ,destination etc. and you can get a pretty good idea of the cost, then increase that price by 10-15% it's not easy packing sculptures to ship abroad or even local. Calculate your boxes and your bubble wrap and tape and labels, it all cost money, consider Insurance A must! That's how I did it, here on FAA I really don't know since your on your own with sales of originals.
btw, nice sculpture!!
