This is: the "Isle of Man Post Stamp Collection" to honor the film "Harry Potter and the Goblet of Fire," from 2005. The Isle of Man issued this folio, which has 6 mint stamp sheets in it, all celebrating Harry Potter.

This folio also has an official First Day cover with the First Day cancellation. The folio is new, complete, and unused.

This would be a great addition to any Harry Potter collection!
