The Bobbsey Twins 'Camping Out' 1955 Edition with Dust Jacket

Grosset & Dunlap New York, 1955 Good condition, I've included photos of a few issues: Dust jacket is whole with one small rip and it is a bit rough around the edges. The back cover has a blank where there used to be a price tag. There is an envelope stuck to the inside. It looks like it may be a makeshift library card pocket, but there are no other marks to indicate it is ex libris A break between pages at page 137. Pages 43-54 have some marks on the edges.
