Polish street artists have been given spray paint and access to a sprawling construction site to commemorate 63 artists who took part in the Warsaw uprising 68 years ago.
From across Poland, 63 artists converged on the capital for a "Graffiti Jam" to paint portraits of photographers, cameramen, poets, painters or actors who were active during a 63-day uprising that erupted on August 1, 1944.
"True Bob," from the northern city of Bydgoszcz, was given the name of Stefan Lewandowski, a photographer who took pictures of the insurrection with a medium-format Rolleicord camera that belonged to his aunt.
"Yesterday I did not know much about him, just that he was 15 at the time," the 17-year-old graffiti artist explained as he sprayed away.
"He did not take part directly in the fighting, which is maybe why he survived and is still alive," Bob added.
The Warsaw Rising Museum has provided cans of spray paint while a real-estate developer at a building site nearby has offered 400 square metres (4,300 square feet) where the works will be on display for a year.
"We are not offering young people a pre-fabricated version of history," museum director Jan Oldakowski told AFP.
"We want to encourage them to go look for information on the uprising and its figures."
Polish resistants fought occupation troops for two months, trying to liberate the capital before Russian troops arrived.
The insurgents gave up on October 2 1944, after the guerilla warfare had claimed the lives of around 18,000 resistants and 17,000 German soldiers.
Another 200,000 civilians fell victim to massacres and 500,000 survivors were deported, after which Hitler ordered that the quarters where the fighting took place be destroyed.
