This is cool but does NASA get a licensing fee? If not then I'm thinking U.S. taxpayers should be getting the other 75% of the profit. The reason I ask is that I am doing a similar thing in my home except that the photographs I'm using don't come from the government - they come from commercial photographers and I'm pretty sure if I sold them in this manner there wouldn't be any profit left for me. If I'm missing something please set me straight.
This is kind of light on the 'how'. Is it possible to do it with other images? If so, what are the minimum specs needed? I imagine there are many great photos in the NASA archives that people would love to get framed.
