Who sent you this lovely fish? That's often the question when it comes to the first day of April and the French tradition of April fish. People in France don't do it much anymore, but they used to send each other cards with fish on them accompanied by messages of affection. Often the card included only a simple message, such as 'guess who.' I have posted many of these Poisson d'Avril cards over the past few years. If you go back to the first post, you can read about the history and traditions of the holiday.
I love these cards because the combination of fish and romance seems so unlikely, but then again, it's fish, romance, and humor - the best combination.
Here are the backs of the first card and the last card.
