I really like your vision and think that it would look great. But at what expense to produce it and how to sponsor the cost, plus, something to consider after incurring these expenses is what Jack mentioned ya think they would work for something your going to pass around. What happens when the next guy says "No, I am keeping it".
As for the cost of the plaque, I think that is pretty much taken care of.
As for an idiot keeping it and not passing it on.....
I may be F.E.O. (
some of you know what that is) but I keep my word,
and that is one of the things I am trying to encourage others to do in this contest.
for example
Don't say you got a Crab "THIS FRIGGIN BIG" if you won't back it up!
Don't offer a prize if you aren't going to pay the winner!
Don't accept the trophy, if you are not going to pass it on to the next winner!
We can do something like ask the winner to mail us a signed commitment to return the trophy after a year, as it is simply on loan to them for one calender year and then if they didn't turn them over to the feds for Using the US MAIL for purposes of fraud and theft. Usually a call from the local postal master will get someone into gear.

I expect people to be honest until they show that they are not,
then I deal with the problem.
Nobody likes how I deal with their dishonesty.
