Who Knows?

I have a beautiful copy of Arabian Knights that I found a couple of years back.  I love the illustrations so much it makes my head spin, but I don't know the artist's name!  The only information I have on the book is that it was first published in Great Britain in 1968 by Ward Lock Limited.  The stories are retold by Anoif Maharg.  There is no mention of the illustrator.  A few of the pictures are signed BAR.   If any of you are familiar and know the artist's name, please tell me!
