It's a complete block (catalogue number block76) from the Isle of Man featuring Prince William's 2010 engagements.

The PROPHILA COLLECTION brand guarantees top quality, which is important when you're building a serious collection.

Whether you're specifically collecting Prince William memorabilia, British Royal Family stamps, or Isle of Man issues, this complete block is a nice addition to your collection.
