Hmm. The cynic in me is saying 'revealed once project is funded. It will be worth it' basically means the print has yet to be decided or created. And the funding from the project would be used to do so at a later stage.
I could understand this to an extent. The aim of the Kickstarter is to fund the production of the goods on offer, and it's likely that only so much money was set aside at the beginning for the creation of the prototypes to draw in business. Not everything can be created up front.
That said, given the cost of the Master Set, I would expect at least a rough idea of what to expect, even if it's a description or a quick sketch. As Phoetux said, everyone will have their own opinion of what constitutes good value to them. $1500 is a hell of a lot to pledge in blind faith.
Speaking of signed prints- I'm still waiting for my NNT naming comp. print OWI
