This is an antique French Encyclopedia dated back to the early 1800s, with fluffy (technical term :)) pages.  This was found in at a Paris flea market.  It measures approximately 9 by 11 inches.  Because this book is over 200 hundred years old there are signs of its history, such as water marks, stains, tears, missing pages, damage to bindings and possibly other imperfections.  Please note that the colors may appear slightly different in person.
