Tight, clean, flat, square and sharp book in DJ with nicks, tears and folded over chips. First edition thus (per ISFDB) with H03 in the gutter.

Little Fuzzy, one of a species of creatures that is short, hairy, intelligent but not advanced beyond the stone age civilization, first appeared in 1968, a generation before they seemingly appeared as the major players in the battle for Endor in Return of the Jedi.  The omnibus appeared 8 years before the movie. This book contains the first two tales of the Fuzzies.

The Fuzzies is a sub-series set in the Federation Universe of H. Beam Piper (his real name) launched in 1957.
