Update: The review is up
The insanely talented and hardworking Kim Jung Gi is releasing his 2013 Sketch Collection art book.
It's going to be around A4 in size with 536 pages. It has slightly less pages than the 2011 Sketch Collection but I don't think the book's going to be that much smaller.
The 2013 Sketch Collection cost US$68, not including shipping charges. The book's mailed from Korea using EMS, and Asian countries generally will have cheaper shipping fees.
Order via email from David, Kim Jung-Gi's assistant. Paypal is accepted.
You might want get all three sketchbook collection at one go if they are in stock. They are very good.
Here are some preview pictures from the book.
