Let me guess...it wasn't through Lightning Source, Lulu, or any of the POD printers...There was only one printing.
I find THE BUK-PURDY letters a good read. But- I was always a letters reader.The book is scarce, but you aren't missing much.
I paid $35 for the book. As far as I know they are around $50 on ebay.If you find it, don't pay top dollar for a reading copy. You should be able to pick up a "non-collectible grade" copy on eBay for $25 - $30 if you're patient.
Good for you! And a very reasonable price too. I remember the thread and I would have bought it if I did'nt have it already. I think it's an interesting letter book. It's by no means as thick as the other letter books, but there's some interesting stuff here and there.I got a very nice copy from our own Bill R. for $35.
