To purchase prints in sizes other than listed please contact me directly.  Not all images will print large however I have made prints up to 24 by 32 inches with no problem with many of the originals.  It will take about a week for me to get a price quote to you.  Shipping in the US for the 15.5" X 11.5" images (matted to 16" X 20") costs about $15 with insurance.  I will also sell photos without the mat so that they can be shipped in a tube if you wish.  I have been selling photographs by mail for 15 years so I know how to pack and I stand behind what I ship 100%.  If it is damaged in shipment or you just don't like what I send that is my problem, not yours.  All you have to do is send it back, no questions, no bitching, I will just return your money, give you another photograph or whatever you want to do.  Selling art by mail involves a leap of faith and I realize that so I want it to be as painless as possible for you.
