Cover of the day comes from the superb Gold Key reprinting, BBCtv authorised, weirdly coloured 'Star Trek Annual' from 1972.
For those outside of the UK (and not in the know) these annuals were released on the run up to Christmas and usually featured reprint material with some added text pieces and puzzles.
Mostly aimed at keeping the kids quiet over the holidays in the pre digital age.
They were actually pretty cool and nearly all hardbacks that many I have kept to this day.
This particular annual however was a 'Comics Club on Tour' purchase at the ever reliable Notting Hill Book Exchange for the princely sum if £2.
Can't be bad.
