Last week I read an article in Publisher's Weekly about a grown-up Scratch'n'Sniff book about the elements of wine. (Frex, when someone describes a wine as having 'woody' tones, do you know what that means? This book shows you, er smells you, er... you know what I mean.)
While the topic itself fascinates me, I found one line to be rather humorous. Thus they say:
"[the publisher] has not attempted a digital edition of the book."
I guess Smell-o-vision is out of fashion on the Internet.
