Review for LEGO set 6991 Monorail Transport Base from Brickset
Best of the Classics — “If you have the chance to get this set, GET THIS SET! It is probably the best set of the 90's, and possibly one of the best sets ever. It truly is an amazing set. If you can get it, get it. The front of the box flips up to reveal more pictures, and some transparent wrapping... More exposes the pieces, nicely sorted in a plastic tray.”
