The Shannon Martin greeting cards combine funny, vintage photos (in sepia tones) with witty greetings for birthdays, anniversaries, and more. We are always amazed at the clever captions and sentiments expressed in these cards. Our customers can't seem to get enough of them, so we keep well-stocked. Shannon Martin cards are printed in the USA with soy-based inks on 100% recycled, acid-free paper made with 100% certified renewable energy. Our mothers would be proud! All cards come with an envelope.
