Some interesting "leaf-trees" for the Hobbit - hard to say what the artist had in mind unless it's Lonely Mountain? Or a very tall Bag End?  The middle is a 2001 Houghton-Mifflin issue with artist Peter Sis giving a sort of "patchwork" of simplified vignettes from the tale. The last is some Czech Hobbit artwork, a fold-out of the 'unexpected party,' and with it (smaller) the front cover of the issue it came from. Thanks to Narquelie for identifying this odd piece, and finding the cover.
