These are 5 identical cards, blank inside with white envelopes

5 extremely silly christmas cards. Viewed the right way up they show an angel happily gliding over snowfields with pine trees behind and the message "Merry Christmas". Viewed upside down (first photo) they show a group of very scary snapping crocodiles about to devour the hapless angel with the message "Many Crocodiles" written below. Display whichever way up you like.

The cards are blank inside and come with envelopes.
Folded size is A5 / 148 x 210 mm / 5.8 x 8.3 in
