Here's the situation. My great uncle is a DO and told me he would love to write me a letter. But he has been retired for about 15 years and doesn't have any professional letterhead--in fact he doesn't even type! My grandma (his sister) said she will type up the letter after he writes it but I've heard that some, or all, schools expect all letters to be on professional or school letterhead. Is this true? Should I make up some professional letterhead for him? I just don't want it to look bogus, and it almost feels bogus if I do something like that. I know, strange situation. What do you think?
