Apparently, The Royal Mail is producing a set of postage stamps to commemorate England's win over Australia in cricket's Ashes Series. The series of stamps will be sold as a sheet of several different value stamps. One of those stamps will have a face value of 68p, the cost of sending a letter to Australia. It's nice to see a large corporation have a sense of humour about these things, especially one as po-faced as The Royal Mail normally is.
I imagine this stamp set will become quite collectible to philatelists in future years compared to other contemporary stamp sets.
