Very interesting earliest American version. You will notice that this copy only says "Harper" on the bottom of the spine. That is because this edition was published before the Harper & Row Version since the Publisher was still Harpers Brothers until May of 1962. This will be the earliest version that was available in the US. 

TRANSLATED FROM 7TH GERMAN EDITION BY J. MACQUARRIE & EDWARD ROBINSON / FIRST PRINTING WITH "COPYRIGHT 1962 BY SCM PRESS LTD" This is the first American Edition that says at the top of the front flap (priced 12.50)

"Harper is privileged to present the first publication in English of Martin Heidegger's "Being and Time" and whose back panel is blank and there is 0862 near the bottom of the front flap.

Also the copyright information reads "Copyright 1962 by SCM Press Ltd."

(SCM Press is the UK publisher of the first edition. All subsequent Harper printings have SCM Press replaced by Harper & Row.)

D.J. HAS MODERATE WEAR/RUB WITH SLIGHT LOSS AT THE CORNERS, SHALLOW 1/8" CHIP AT THE TOP OF THE SPINE PANEL, A FEW SHORT EDGE TEARS, AND IS NOT PRICE-CLIPPED. AN EXCELLENT CLEAN, BRIGHT, AND TIGHT COPY.
