Take very good, clear pics of it, the more the better.. describe any damage it has, if any, and any staining that doesn't wash out. Do all that and you will have no problems. I suspect that one will sell pretty well..
Janette: I collect that type of bottle and can tell you that you definitely need to describe the size / height of it as there are several different sizes and that is important to collectors going for a lineup. It's a nice piece, look to get $100 + for it.
If the buyers are willing to pay for the extra shipping costs, shipping overseas is a good way to make extra money. Sold bottles to Australian, British, and South African buyers no problem. Maybe you could compromise and allow shipment only to fellow English speaking nations? Just today, out of 6 orders shipped, 4 were to foreign buyers in Italy, UK, Serbia, and Finland. First time I've shipped anything to Serbia. Allowing for international shipping is crucial for me.
