I'M NO EXPERT! I'VE DONE NO RESEARCH! This two-sided stock page was found at an estate sale (I think it's old dealer stock), the page is under plastic, but it can be removed and stamps will be loose and removable (looks like about 140 stamps). I THINK THEY INCLUDE - Mexico, Finland, Sweden, New Zealand, South Africa, Rhodesia, Japan, etc..... WHAT YOU SEE IS WHAT YOU GET! ... code Jsb 332
