If you'd like to clear out your bookshelves and make a few quid, send us a list or a picture of what you've got to email@example.com and we'll see what we can do! Minus a few odd exceptions, Little Deer won't really be dealing in Marvel or DC and probably no serialized trade paper backs either. Only self-contained, single volume stories for now.
Some gaps I'd love to fill right now: younger comics, such as the Hilda series by Luke Pearson and Owly by Andy Runton. Young adult books by Raina Telgemeier. Anything from the Love & Rockets series by the Hernandez Brothers.
