This is very common on ebay or any auction house or antique mall. Why do you think I have purchased dust jacketed books for 5.00? It does go both ways. If I am interested in an item, I always email for clearer descriptions before bidding. In the case of golden books, the prices can vary by many dollars of the same book....buyer beware. Don't overpay just to get a title.Get yourself a good guidebook for help.
I have been looking at LGB's on ebay and sold a few there myself. But have any of you noticed people selling modern reprints of the older 1940's and 1950's books out there as if they were an original?
