Original Greeting Cards by artist Krista Brooks of Retro Pets® “Works of Arf!” Cards are 4.25 x 5.5 and come with an A2 envelope (either white or colored). On the back of each card is a fascinating, funny fact about the featured breed, plus a more general, animal-themed quote. Printed on 12-pt/C1S, (in compliance with the Sustainable Forest Initiative). Krista enjoys capturing the quirky, lovable and laughable personalities of our animal friends. Getting the wording to speak volumes is just as important to her as nailing the look in each perky pet's eye.
