Booklet With Geo V1 And Qe11 Stamps .

I have a Great Britain GPO 1953 booklet with Three different value stamps Geo V1, and two QE11 stamps.This booklet usually contains 36 stamps.It has been used so now only 10 stamps remain.I have had this for about 30 years and never examined it,imagine my surprise when I saw QE11 and her father in the same booklet. I see that the forgery can be accomplished by restitching, the effort would be very timeconsuming like someone with TIME on their hands can anyone tell me anything about this booklet.Thanks in advance.

Your booklet is very interesting...but normal. These are known as Composite Booklets and have ,as you mention, stamps of George VI and Elizabeth 11 in the same booklet.
Complete booklets would have George VI stamp values halfpenny, penny and twopence. The Elizabeth II values are 1.5d and 2.5d

Thanks for the information I am still surprised I never thought that this would be done placing two monarchs together one being dead an all.

Post war Britain had little to waste so any surplus stamp stocks would be used up. The George VI stamps were valid until 1972.
