It was the first publication  of it’s type, predating Starlog. All of the content came from our  personal collections. We were running the Federation Trading Post on  57th Street in midtown Manhattan, and Fiona Press  was right across the  street. Somehow they ended up with Trek publishing rights. What did they  know about Star Trek? Nothing! In those days if you wanted Trek info we  were the only game in town and they fell right  into our gravity well.  The next thing we knew, we had our own magazine!
My single favorite issue is  this one…” The Smithsonian Report – A Pictorial Inspection of Star  Trek’s Miniatures Today”. The Air & Space Museum in Washington D.C.  let us in before the doors opened, and even gave us a ladder to get up  close and personal with the TOS Enterprise filming miniature. I was in  heaven. I climbed the ladder with anticipation, and planted one on the  leading edge of the saucer. 
So here it is, Poster Book  issue 10 – ” The Smithsonian Report”. I’ve scanned it at extra hi rez,  give it a click and enjoy the slingshot! 
Note that you can click on these images and see close ups so you can read them. Also, this issue of the Poster Book is readily available on eBay with a BIN of about $ 15. I just bought one myself.
