The images were placed in sidewalk billboards and picture a figure in a purple mask and red cloak, garments reminiscent of the bright clothes that are one of the band's trademarks. At the top of the signs are the letters "SVBD PSRT," apparently a shortened version of the message "Free Pussy Riot."
Photographs of the signs were posted on the website of magazine Kissmybabushka.
Nadezhda Tolokonnikova and Maria Alyokhina were arrested last week after Pussy Riot's five-minute performance Feb. 21. A Moscow court ordered the two women to remain in custody until April 24 while they await trial on charges of hooliganism.
At an opposition rally on Saturday many demonstrators held signs calling for the release of the jailed band members. Representatives of the Orthodox Church have said they believe the two women, both of whom have young children, should be let go.
A Message from The Moscow Times:
Dear readers,
We are facing unprecedented challenges. Russia's Prosecutor General's Office has designated The Moscow Times as an "undesirable" organization, criminalizing our work and putting our staff at risk of prosecution. This follows our earlier unjust labeling as a "foreign agent."
These actions are direct attempts to silence independent journalism in Russia. The authorities claim our work "discredits the decisions of the Russian leadership." We see things differently: we strive to provide accurate, unbiased reporting on Russia.
We, the journalists of The Moscow Times, refuse to be silenced. But to continue our work, we need your help.
Your support, no matter how small, makes a world of difference. If you can, please support us monthly starting from just $2. It's quick to set up, and every contribution makes a significant impact.
By supporting The Moscow Times, you're defending open, independent journalism in the face of repression. Thank you for standing with us.

Remind me later.
