1914-17 Pierce Arrow Truck Ads

Probably 15-18 1914 to 1917 Pierce Arrow truck ads on outside back covers of a business trade magazine named American Industries; were bound in books but now separated. 8x11 on an odd soft almost pulpy paper with a kind of light sepia tone. B/w (black/sepia?) except for green or orange outline, still attached to front cover for date verification. Probably 10-12 different ads (a few duplicated); about 1/3 page illus plus text. Good cond but because of paper should be either framed or kept in clear protectors. Price $1 plus mailing individually, consider less for part of batch/set of ads.
