As a "Thank you" for your contribution I will send you a a specialty post card once I am in the field with a unique picture from Kenya
In addition to the above, I will bring you a magnet or other small trinket as a thank you for your generous donation.
Of course, within reason - I will get you the souvenir of your choice upon my return from my fellowship.
A "thank you" video from the summit of Kilimanjaro and a piece of land from the highest mountain in Africa! I could bring you a postcard too :)
