Three 1931-1939 Bolivia Postage Due Stamps - 5, 10, 30 Denomination.  These are from my personal stamp collection.  My Grandfather and I sat for hours in the mid 1950s.  When he died on October 5, 1958, I lost interest in stamp collecting.  I am now in my late seventies and no longer wish to pursue this hobby.  You will have to judge the photos for yourself.  These stamps are mint and hinged.  You are buying these stamps as is.
