Lots of the world pages have stamps as well, some pages blank, some have just one or a few and others have several.  Looks like may be early century there as well, but I am not familiar with world stamps. 

Some stamps appear stuck to page, I think most are either hinge or mounts. 

Most of album in good shape, areas where you can see stamps have been removed, few pages stuck together, etc. 

War era, Germany stamps with swastikas', Russia,  Special Handling, Western Union Telegraph stamps, and MORE! A wide variety!
