I was thrilled to find a copy of this tonight. I'd seen and coveted a friend's, which she got for her new granddaughter. My nieces are both too old and too young to appreciate it, which means I get to keep it for myself.
If you can't read the lower right corner, it says, "a counting primer by Jennifer Adams" (Alison Oliver is the artist). This is the cleverest thing, well worthy of Jane Austen. The numbers are represented by characters and events from Pride & Prejudice, with funny illustrations, like Elizabeth on the cover above, in a top that reads "I ♥ Darcy." The number 2 is "2 rich gentlemen," Messrs. Bingley and Darcy. The number 4 is "4 marriage proposals," though sadly Mr Collins's to Charlotte is not included. My favorite number is 10: "10,000 pounds a year."
I see that the same team has also done Jane Eyre and Romeo and Juliet. I'm hoping for Emma or Persuasion, myself.
