Published by the Daily Express the year after World War 2 ended, paper was still in short supply so War Economy Standard was still in use and the annual was produced with soft covers.
If you are a Rupert fan you may be aware that most of the Rupert annuals from the very first one (1936) to the 1970 edition have been reproduced in facsimile editions. However, a few of them haven't due to politcally incorrect content and this is one of them. In fact, it is the first of those not to be reproduced. It has now become very scarce as Rupert collectors want to collect the full set and without a facsimile of this edition they have to buy the 'real thing'.
