Enjoy exploring these galleries:
America's Parks, Forests, and Wildernesses
You can purchase prints on a large range of substrates, and also, phone cases and greeting cards.
I use Fine Art America as the printer.
Fine Art America does an amazing job producing prints on a range of papers, canvas, or metal, and with many matting and framing options.
I love the luminosity of the metal print which I use for my personal collection.
Prints are available in a wide range of sizes. The larger a print, the more impressive it is, and the more it costs.
When looking to purchase a smaller-sized print, opt for at least a size of about 12"x8". Smaller prints are nice for collecting, and decorating a room with several prints from the same subject.
For eye-catching statement pieces that will be placed on a wall by itself, use a print size where the long side is at least between 20" and 24".
