These are only “scratch” versions, but they should give stamp collectors and fans an idea of what the 20 stamps will be. As mentioned previously, each stamp is approximately 1.56″ x 0.89″ and the entire pane of four, plus selvage is about 4 inches square.

And here are the postmarks: 

The B&W or “hand cancel” postmark is 1.733 x 1.222″. The Digital Color Postmark is 2.398″ x .986″

There are four subjects per sheet inside the 20-stamp booklets. Two stamps per page are vertical, two horizontal. Here’s what I’ve been told is the list of stamp subjects:

The first pane is from the first film. The stamps show Harry receiving his acceptance to Hogwarts; Harry and Ron; Harry, Ron and Hermione; and Hermione.

The second pane shows Harry and some of the creatures in the stories, including Hedwig, his owl.

The subjects in the third are all Hogwarts instructors: Dumbledore, Snape, McGonagall, and Hagrid. It appears the stamp shows Michael Gambon as Dumbledore, not Richard Harris, who died a few weeks before the release of the second film.

The fourth pane has a picture of Hermione, Harry and Ron; Ginny Weasley, Fred and George Weasley, and Luna Lovegood.

And in the fifth, we’ll find pictures of Harry and Voldemort in battle (the former design has already been released publicly and is shown here), Draco Malfoy, and Bellatrix Lestrange. The latter strikes me as a (le)strange choice, because I don’t think she’s a major character. I would have picked Neville Longbottom for one of the stamps, or, if pressed for a female character, Molly Weasley or, even better if they wanted a female villain, Dolores Umbridge.

There is a red sealing wax seal in the blank space in the middle of each pane. There’s a picture of Hogwarts (castle) one another page of the booklet.
