With a few days left in the Month of Letters Challenge, the UK Royal Mail has issued six “gloriumptiously” collectible stamps for Roald Dahl fans.

Here’s more from the description page: “Six of Dahl’s most popular children’s stories feature on the Stamps – Charlie and the Chocolate Factory, Fantastic Mr Fox, James & the Giant Peach, Matilda, The Twits and The Witches. As many of Dahl’s best loved stories have been illustrated by Quentin Blake it made perfect sense to use his illustrations for these Stamps.” What is your favorite stamp?

Each stamps contains a pivotal moment in the Dahl stories, from Mr. and Mrs. Twits‘ upside-down escapades to Charlie Bucket‘s golden ticket discovery. Prices for the stamps start at 66 pence (approximately $1.03 USD). A sheet of six sells for £4.66 (approximately $7.30 USD).
