Sierra-Enterprises.com was the first website to carry PSX stamps and had a huge inventory. Some of these stamps were stored in boxes and lost in warehouses. Lately we have come across boxes that contained some new finds. Granted some of these are not the large 'K" stamps yet there are some smaller stamps with fantastic detail and delicate images that are not available anymore. You may want to take a look at these stamps if not to buy just to see some Beautiful images.
