Pin-up images are widely associated with voluptuous women in the 1950s and '60s, Playboy centrefolds and Bettie Page.
Pin-up drawings, which have roots that go all the way back to the 1890s, are also becoming trendy again, with artists re-interpreting the vintage images with modern twists.
One such artist, Valery Barykin, mixes '50s themes and communist propaganda into classic retro pin-up drawings.
Some of his illustrations are making the rounds again and are generating a lot of discussion around their imagery and purpose.
Barykin, a Russian native, draws classic pin-up girls in revealing, tight outfits but includes modern technology such as smartphones and flat-screen computers.
The illustrations feature traditional Russian slogans such as "How much did you worked today?" and "Worker of the communal services! Provide the best quality of service in your home!"
What do you think of the drawings? Is there still a purpose for pin-up girl illustrations?
