Zach (or is it Zack?) was a Lego maniac, or so the ads told claimed. I remember seeing this ad in 1987 and thinking the kid was pretty full of himself. Look at him stacking away like it ain't no thing.
As a card carrying member of the LEGO Club in the 80s, I was likely just jealous of Zach and his rock n' roll Lego wild lifestyle. I mean, who wouldn't be?
