Query: Historical Medicine, Wound Healing

Excellent historical work regarding wound healing. If one can obtain the original edition of 1975 in good condition, I find it preferable to the reprint of 1992 in that it is paperback rather than hard cover, slightly smaller than the original and the quality of the photos and such were not reproduced all that well in the re-print.
