Several years ago I took my old trains out of the attic to create a lay out of approximately 12 foot by 9 foot. A lot of the stuff is quite old (going back 50 or more years) and were still in their original Lionel boxes. My understanding is that the value of some of these older items are enhanced if they come in their original box but many of these old boxes are falling apart. I can use scotch tape for box repairs but is there something better?
