DGR did this drawing when he was with Lizzie at Scalands, as his letter to Madox Brown (23 May 1854)
shows: “Lizzy, poor dear, continues on the whole much the same. I have been here rather more than a fortnight, and shall now be returning for a short time to London, leaving her here till I can come again. She is looking lovelier than ever, but is very weak though not so much as one might expect. She has walked a good deal till the last day or two, when we have been working. She has spent two very pleasant days at Barbara Smith's farm some miles from here, and just while I write a letter reaches me asking us to go down again to-day, but I do not suppose we shall as it is wet. Everyone adores and reveres Lizzy. B.S., Miss Howitt, and I made sketches of her dear head with iris stuck in her dear hair the other day”
