I'm not a record expert, but I believe this to be factory sealed. It's in fantastic shape. I tried to get pictures of the seal to demonstrate it is on there tightly. I do not see any visible tears or holes. There is not any ring wear present, and the spine is fully intact. The only year I can find anywhere on this is 1966, so obviously it looks great for its age. If you have more questions, please don't hesitate to ask. Also, don't be afraid to make offers!
