This is the cover I've made and was used as cover of the Abando's conbook this year. The theme was feudal Japan.
The cover was made in two wood blocks using Copic markers, white ink and collage with origami paper in Okinawa Kimikiri style.
It was made considerating the person arriving and lefting the con. So, the front cover (in the right) is named "Welcome to Daimyo's Domain", and the back cover (at left), "I Wish We Can Meet Again".
It's the 4th version of the front cover and 2nd of the back cover. I'll post the other versions soon. I hope I can post the final version of the cover later too...
