[10] Greek writer Makis Malafekas based his pulp-noir novel "De les kouventa / Δε λες κουβέντα" [11](Athens Undocumented) on the events that took place at the Old Carpet Factory mansion with one of the main characters drawn from Stephan Colloredo-Mansfeld.

"The Warp of Time" book published by Mnemosyne Projects in 2024 tells the history of the Old Carpet Factory mansion and its owners from Anastasios Tsamados to Stephan Colloredo-Mansfeld.
