Condition - The light purple cover with brown design border and black print appears to be unfaded. There is a crease going down the length of the front cover about 2 ½ inches from the spine edge at the top angling down to about 1 ½ inches from the spine edge at the bottom. This crease is clearly evident on the inside of the front cover. Some adjacent creases are noticeable on the front cover but not nearly as visible inside. The outer edge of the front cover has some minor small creases and normal handling wear. The spine edge is only very slightly rolled from probable stacking of the magazine. All spine edge print is intact and clear. There is slight fraying of the paper only at the extreme top and bottom of the spine edge. There are no markings in the magazine-journal including no previous owners names. Two adjacent pages have smudge type stains including what looks like an outline impression of some object (looks like partial shoe print). There are several successive pages with an about one quarter inch bottom of the page edge tear and the last page in the magazine has an about one inch outer side edge page tear. Advertisements and text pages are clear with only mild normal age yellowing of the pages. The back cover has an about one quarter inch inward edge tear and some scuffing from storage. There are no missing. Loose creased or marked pages. The magazine is in overall very good condition. Buyer pays S &H. Payment must be via paypal.
