The inventor had professional-looking stationery and wrote a concise letter that piqued the reader's interest. Included was a description of the invention as well as any honors or acclaim it had received. Answer these questions. Include some, but not all, of the same information described above. When possible, they sent me a sample of their invention.

If you are sending your information to someone who will be promoting you, they NEED to see your invention in order to better understand it. Understanding brings enthusiasm. If you are an extremely articulate communicator, as well as a talented writer and designer, it may be possible to do all of the above by yourself. You don't want your brochure to look handmade-even if it was. The information you send out about your invention is almost as important as the invention itself.
