Here we have "Yeti Attack" containing the two Troughton yeti stories and "Adventures in History" containing the three historicals shown underneath. I understand that "The Massacre" has the distinction of being the only Dr. Who story which does not have a credit on one of the episodes for "Dr. Who" or "The Doctor".

By the way, I hope you enjoyed the varied and artistic ways I laid out these audio releases for you in these photographs!
