This is a super rare mug with artwork on it by Cathy Guisewite who is the artist that created the Cathy comic strip.
Unsurprisingly this mug features a Cathy comic strip that pokes fun at computer talk. Please see the photos to read the comic strip, which is quite humorous.
Underneath the comic strip printed in a large red font is:
"Apple Canada In Education."
There are red apple symbols both before and after this.
