Most of the poems and pieces I have copies of, as I have worked in archives with the original magazines for most of them (or clippings that Plath herself retained). However, the June 1947 issue was partly elusive. Her poem "May", appearing on page 26, was clipped by Plath and now resides in an archive. But her "Class Poem", which was published on page 11 of the same issue, does not seem to exist and I have been looking for it for about twenty years. I have photocopies of, I believe, all of Sylvia Plath's published poems except for this one. It is rather curious that Plath chose to retain "May" for posterity, but not her "Class Poem".
In the odd way that coincidences happen, a copy of the June 1947 issue, with missing pages, and an earlier Phillipian from April 1945, was offered for sale today via a Bonhams auction in New York (Lot 135). The estimate was US$ 1,500 - 2,000 | £ 1,100 - 1,400. It appears not to have sold, though the hammer was sounded with bidding at $1,200. I guess, maybe, because the low estimate was not reached?
My most sincere thanks to Taylor Kolloch at the Wellesley Historical Society for supplying a copy of the the poem and yearbook photographs from the June 1947 issue of The Phillipian.
