Lego city road base plates vintage 1978

This set of vintage Lego road base plates are an amazing find! These have been owned by my family and have been stored in a box. This set includes 13 gray street base plates. 8 of them say 1978 LEGO A/S Interlego AG. 5 of them say LEGO A/S Interlego AG on the back. This is a true find for the Lego collector. They measure 10x10 each. They are in excellent used pre loved condition.
