What is the "classic" tolkien hobbit cover artwork called?

It is called The Hobbit dustjacket 1937 (MS Tolkien 32), by the Bodleian Library. The MS Tolkien 32 describes the location in the library where the original copy is stored of the artwork, this copy was used by the printers to create the published dustjacket.

I am not aware that Tolkien named this artwork but the dustjacket also contained text in the runes that describe the contents of the book.

Thanks!!
