Ooh, look what that extremely nice TWO-HEADED BOY (from Two-Headed Thingies) sent me recently. The BIRTHDAY BOOK For BOYS 1972, featuring strips and text stories from various comic periodicals that were available way back then.
Interestingly, the interior copyright date of 1972 suggests that perhaps it wasn't a Christmas Annual because, as all British readers know, the copyright date is usually that of the year an Annual is issued, not the year it's for. (So, Annuals cover-dated 1972 for example, went on sale in August or Septermber of '71, and usually carried the year of issue inside.)
The purpose of the Annual was obviously to entice readers to hunt down the weekly comics which featured the particular stories they'd enjoyed and thereby increase circulation. It would be interesting to learn whether the project ever bore fruit, but as far as I'm aware, the experiment wasn't repeated, so I think we can safely draw our own conclusions as to the results (or lack of them). I'm bound to say that I think they missed a trick by not including ADAM ETERNO.
Anyway, take a look at a few of the contents and refresh your memories of your long-ago youth. If you happen to know whether this book was issued at the end of '71 or sometime in '72, feel free to enlighten me in the comments section.
