Where'd you get the images from ?
The second one is from a guy who had an engravings collection of Koonfur on some collectors site. He made the preview pics pretty damn high resolution so I had no need to purchase his originals:
The first is just from a google search of "Qur'an wood boards, Somalia". A lot pop up. These are still actually used in the rural areas of Somaliweyn to this day.
