nly slightly. Tolkien described Bilbo thusly for purposes of
illustration in a letter to Houghton Mifflin (c. 1938):
I picture a fairly human figure, not a kind of 'fairy' rabbit as some of my British reviewers seem to fancy: fattish in the stomach, shortish in the leg. A round, jovial face; ears only slightly pointed and 'elvish'; hair short and curling (brown). The feet from the ankles down, covered with brown hairy fur. Clothing: green velvet breeches; red or yellow waistcoat; brown or green jacket; gold (or brass) buttons; a dark green hood and cloak (belonging to a dwarf).Letters, 35 (#27)
The Annotated Hobbit cites this letter and includes a reasonable illustration based upon it. (Note that Tolkien's use of the word "elvish" here refers to the Elfs of popular folklore, who were often pictured with pointed ears. The Elves of Middle-earth (except for the Silvan Elves in The Hobbit) were at the time of this letter known to only a few people.)
