I am trying to get a piece of art, representing 9/11 fallen fire
fighters and police officers, made into a postage stamp.

The Post Office does not accept unsolicited art, this is policy, not law. 

There is a lot of local support, testimonials from Oregon Senators,
firefighters and others are on record. The project has hit a log jam
after nearly three years of pushing, with the ?no? (claiming policy)
coming from the postal board itself. (There are no immediate plans to
commemorate 9/11 at this time)

However, the people involved in this activity are not ready to give up yet.

The goal is to create a stamp that will also double as a fundraiser
for fire fighters and police officers.

These are my questions:

1. Has anyone ever succeeded in ?bucking the system? and getting a
stamp made that wasn?t formally commissioned?
2. What steps should be taken to make this happen? Is there a probable
success rate?
3. What is the process for getting a stamp made?
4. Please provide me with links and contacts for creating a successful
grassroots campaign
