That is a great find, especially with the vintage country flags and coat of arms! I
inherited Volume 1 from my father in law, since he only collected US stamps. Then I felt encouraged to buy the next nine volumes. I got lucky at a stamp show and won five volumes for $10 each! The rest I purchased through
ebay for between $30-$50 each. The first ten volumes roughly cover the time period 1840-1975, which is the majority of my collection. There were approximately 500 stamps in each album; definitely a great investment! Now, I am just focusing on fillers for sets.
