Giving your passport to the customs official is exciting! It is so fun to get another stamp in your passport. The book is nicely divided into pages with squares that are so easy to stamp. How many stamps does it take to fill your passport? How many per page? Some officers do not respect the geometric boundaries set in the passport. Instead they overlap stamps and stamp on top of the lines. How many stamps can your passport hold if the square boundaries are not utilized? Not all stamps are the same shape either. Some are round, some oval, and still others rectangular.
