Delicate folio watercolours of interior decoration. With the title page in watercolour, a leaf with water colour coat of arms, eight watercolours showing interior views (most of which highlighted with silver and gold, one signed 'Herssens'), last leaf with a manuscript inscription reading 'Les Ateliers H. Laureys étudié par E. Herssens,' all interleaved with tissue-guards. Contemporary green cloth with gilt lines on covers, endpapers with green floral pattern. A unique collection of watercolours showing interior views by E. Herssens, probably depicting a mansion owned by Madame Hubert le Hardy de Beaulieu. Nothing was found about 'Les Ateliers H. Laureys' nor about the artist E. Herssens, who signed one of the watercolours. Joints weak and partly cracked, corners bumped. The watercolours are in excellent condition.
