Marked as used, but this paperback 33 page booklet printed in 1962 and listed as a first edition second printing looks to have been bought and stored without it being read ….. being over 60 years old the cover and edge pages have slightly yellowed, and there are some very light rubs to the corners of the cover……… stapled spine is tight….. there are some very nice and detailed topographical surveys of the various movements of the ice at that time……. Very suitable for small framed decor
