Continuing with the retro Target books, here's season 13.
It was during this season that I queued up outside Preedy's newsagents in Derby's Eagle Centre in order to have a fully costumed Tom Baker sign my copy of 'Doctor Who and the Dinosaur Invasion' - an odd choice since it was a Jon Pertwee adventure but it was at the time, the only Target book I didn't own.
From that day until today, I had a complete set of first edition Target books (except for 'The Two Doctors' which is a "Second Edition" due to a f*** up at W H Allen.)
These covers are available as design on RedBubble.
