1992 A Field Guide To Eastern Butterflies By Paul A. Opler, The Peterson Field Guide Series, Butterfly Reference Book, Vintage Butterfly Ephemera

Approximately 7 1/8” x 4 3/8” x 1”. In used vintage condition. There’s writing on the cover as well as a note written on the first page. There is a section in the back where you can check off butterflies you’ve seen and some have been written next to in pencil. Some creasing to a few pages. In the center of the book the binding is kind of “split” when you open it, so it lays flat (see photo #15).
