Recently we found another 20 year old sealed puzzle that just looked like an excellent Ebay item. It is of the Palace Gardens in Williamsburg and it is a two-sided puzzle! Brand new in package! When looking for puzzles that might sell well on Ebay, keep in mind some very basic hunting points. 1- Buyers like sealed puzzles so they know for sure (in most cases) the item is in great condition. 2- If the puzzle is not sealed, assemble it to show them it is complete 3- Does the puzzle image interest you? If so it might interest buyers 4- Look for odd puzzles like different shapes, two sided puzzles, glow in the dark aspects etc. Good luck hunting. Here is a picture of our recent two sided Eaton Puzzle from the 1980s we are currently selling.
