Personal stamps

Some nice American personal stamps. I did start to collect them, but only by exchange and maybe some Dutch one's by Ebay. These I got from a friend in the States. They are still on paper, I don't know if they soak easy, maybe somebody can tell us and me. Did made some personal stamps myself and today I put one on EBAY. Always interested what the price would be for a worldwide issue of 20 stamps. Do you have a personal stamp, I like to exchange with mine.
