The Litany Of Dagon printed on a handmade scroll.
The scrolls are made from heavy cardstock, which is then treated using different methods to artificially age it - watercolors, teabags, coffee grounds, bleach, and so on. The end result is that it ends up looking like old leather, or like it was scribbled a in squid ink on tanned seal hide and hidden in a jar in the desert for a thousand years.
