Note: One of two "Cardooos" released at the same time — the other is referred to as "Clockwork World" (though this and the title "Queen Amy" just refer to the comic strip inside and don't appear on the outside). "Cardooos" are basically birthday cards with a 16-page activity book enclosed, containing an exclusive comic strip plus stickers and puzzles. (The activity content, plus the fact that they have ISBN numbers, are the reason why I'm listing these items on this site, as I don't normally list "non-book" merchandise like greetings cards.)
Not "just a card"...
It's the DOCTOR WHO ACTIVITY CARD
And loads more activities — for HOURS OF ENTERTAINMENT!
Greeting inside reads: "Have a Fantastic Day!"
