Hey @lonepigeon ! If you ever wanted to offer prints, I had decent results from Office Max. We used both of their large format printers to reproduce a photo of mine and printed it at around 12" x 20" or so and they both turned out decent. One had a better representation of the color of the sculpture and I bought that one. It was printed on fairly heavy gloss paper, not a textured "art print" paper or anything fancy, but it'll look great framed if you ever chose to go that route! There a lots of high-end printing companies out there too though if you wanted to offer more expensive, uber-high quality art prints on really nice paper. I always liked getting prints that were shipped in larger 4"-6" tubes rather than those too tightly rolled and stuffed into 2" tubes. I was always afraid of the prints that were shipped flat because they come in flimsy cardboard and almost always came wrinkled, creased, or folded. Anywho, just food for thought!
