Heres my advert for Kazoop it shows all the different things X Ray specs can do..see link above..
This is the last Christmas X Ray Specs Mike Lacey drew Dec 1991 it ended in Feb 1992 becoming reprints (sadly!).... and at this time his X Ray specs could read minds!!
I love the ending of this strip..;0)
Mike could of if he wanted to work for DC Thomson..
Mike still drew very well indeed!
