I have some return cards that I haven't gotten around to selling. I will send a sketch card to anyone who buys my Marty Pants books from Amazon:
https://www.amazon.com/Marty-Pants-Do-Not-Open/dp/0062427768/ref=sr_1_1?ie=UTF8&qid=1498448755&sr=8-1&keywords=marty+pantsJolly Mean vs. Blue Giant - 2 Marty Pants books
Campy's - 2 Marty Pants books
Cap'n Crud/Milk Deads - 3 Marty Pants books

Mr. Mean, My T Fink, Fink, Kentucky Fried Finkers - 3 Marty Pants books

I know this is unorthodox. Marty Pants is a middle-grade book series I'm writing for HarperCollins. I'm trying to boost sales by any method I can, so that's why I'm doing this weird thing. They are about $10 a book on Amazon. Give them out as gifts! Help spread the word and get a sketch for your trouble.
