Portrait painting by Thomas Gainsborough, LeadArt oil painting just do reproduction of them in museum quality on linen canvas:

Thomas Gainsborough (christened 14 May 1727 – 2 August 1788) was a British portrait and landscape painter.
Gainsborough was noted for the speed with which he applied his paint, and he worked more from his observations of nature (and of human nature) than from any application of formal academic rules. The poetic sensibility of his paintings caused Constable to say, "On looking at them, we find tears in our eyes and know not what brings them." He himself said, "I'm sick of portraits, and wish very much to take my viol-da-gam and walk off to some sweet village, where I can paint landskips (sic) and enjoy the fag end of life in quietness and ease."
His most famous works, such as Portrait of Mrs. Graham; Mary and Margaret: The Painter's Daughters; William Hallett and His Wife Elizabeth, nee Stephen, known as The Morning Walk; and Cottage Girl with Dog and Pitcher, display the unique individuality of his subjects.
Gainsborough's only known assistant was his nephew, Gainsborough Dupont. In the last year of his life he collaborated with John Hoppner in painting a full length portrait of Charlotte, Countess Talbot.
