Yarrowstalks was Philadelphia’s Oracle, one of the best of the underground papers;Yarrowstalks was a blend of artwork and creative writing. It was not radical politically, but rather a gently publication, with visually pleasing graphics and an easy editorial style. The first issue includes a 2 page interview with Timothy Leary, with photograph. The paper, following the lead of editor and publisher Brian Zahn, moved toward Eastern philosophies. Twelve issues of Yarrowstalks were published in Philadelphia from 1967 until 1975. Most of the activity was concentrated at the beginning of the period, in the heyday of underground press activity.
