This is a perfect bookend for Standard Complete Learning, featuring various images of optical illusions and a back with an erasable coating.
I remember Standard Jeon, but I think there was a separate Standard Complete Learning section.
A detailed explanation of optical illusions is said to be in the October 1993 Special Edition of Complete Learning, but well... it's just an explanation of optical illusions.
When I was young, these things were fascinating, but now that I'm older, they're not as fascinating.
The back features a schedule with a Saturday section, a map of the Korean Peninsula, and a section for today's homework. It's a wonderful, specially coated bookend.
I'd like to express my gratitude to Shinae, who wrote the homework beautifully.
