Your part of this project will require completing three steps:
Step 1: You provide some historical context for the commemoration Step 2: You choose a look and feel that suits your needs and tastes Step 3: You personalize the product.
When you are satisfied that you have specified your commemoration to your liking, you place the order. The first $20 of your order buys you a pdf of several variants of your specification. You can chose your final, physical delivery from these, or simply stop there and use your lower-resolution pdfs to print and display*.
*(But note that in addition to being at a lower image density than your final print would be, these are watermarked, do not have unique print IDs, and are without my final QA initials - though they will still look pretty great:)
