Rare sketches of Oor Wullie and The Broons are to go under the hammer.
The sale has attracted attention from across the world
The original illustrations are expected to fetch hundreds of pounds when they are auctioned at Lyon and Turnbull's Edinburgh sale next month.
The drawings, which were done in 1938 by artist Dudley Dexter Watkins, feature Oor Wullie sitting on his upturned bucket.
Also featured in the drawings are Maw and Paw Broon, members of the Watkins' other famous creation, The Broons.
Alex Dove, a book specialist at Lyon and Turnbull, said the illustrations were attracting the attention of book dealers from across the world.
The sketches, which are being sold together, come from a private vendor.
It is estimated they will fetch between £300 and £500 when they are auctioned on 5 September.
Watkins devised Oor Wullie and The Broons while working for Dundee publisher DC Thomson.
The character of Oor Wullie is said to have been based on his son.
