In Agatha Christie's Poirot, The Underdog, a portrait painted by the artist Tamara de Lempicka in 1928 has been copied and the face altered to resemble the actor who plays the character Reuben Astwell. Tamara de Lempicka was a famous female artist of the Art Deco era and her works typify the style of the period.
Another example is a portrait from the episode One, Two, Buckle my Shoe that borrowed heavily from two different painting by Tamara de Lempicka.
The boardroom scene in one,Two Buckle my Shoe features a portrait of a couple which was based on two separate portraits by by Tamara de Lempicka as seen below.
