John Smith Legacy is one of the first texture packs for the PC version of Minecraft (and now ported to Pocket Edition). It is a medieval-style texture pack that is useful for giving terrain and structures a more worn-in appearance. If you like packs that are incredibly detailed, this pack would likely be your best choice.
