Some goodies with those cartoon can be purchased from CafePress
All the materials included on this page are free to use, but if you find them useful, pretty please (this is not a requirement, only my humble wish) send an email to dioanad at server gmail.com with thanks for motivating me to publish some content and expressing your unhappiness to the same person for destroying my motivation to publish even more.
Be nice, polite and do not do nasty things with the address above. Thank you.
