Size of stamps

Last month saw the release of a stamp issue celebrating Great British Films...

 However, the size of the stamps is rather large. This is a first class stamp on a C6~ish envelope.

 For the first rate of International airmail, there is not a lot of spare room for the make-up value stamps...  Imagine using this issue on postcards.... and there isn't a nice 97p stamp on the horizon. 

There is just enough room to use two of the first class stamps plus additional postage to for the next weight band of airmail, although there are stamps in this issue for £1.28. 

At least the next issue of stamps, this Thursday 5th June, and all first class, should be of a more convenient size...
