This appears to be a vintage, possibly 1940s, colored lithograph or print depicting a Victorian-era couple in elegant attire, potentially in a French or Rococo style. The illustration features a man in a yellow waistcoat and purple coat bowing to a woman in a pink and orange gown on a set of stairs. The style is reminiscent of the 18th-century French artist Louis Carrogis Carmontelle. It is likely part of a set of similar prints. The print has a visible copyright date on the bottom right edge, though it is not fully legible in the image
