If you've read the book and love Mildred's adventures, you will know that she bought a card from Mr Franks that looked like her cat 'Missy'.
Here is that card!
 
Although the name of the card is 'Happy Gathering', the card is blank inside.
 
All cards are wrapped in cellophane and have a white envelope.
 
Please note that postage for one card is the same as if you order multiple cards, you will only be charged once. This is confirmed at the checkout.
