Thanks to a donation from Joy Ziegeweid, MUP '07, AAEL Images has a collection of 100 images of Russian Constructivist architectural monuments in Moscow. Taken in 2005, the images show the state of the buildings (and often their urban context) at that time. All images are licensed CC BY-SA, so anyone is free to use them with proper attribution! We're showing some lower-resolution versions here. For the full collection with a range of image sizes, just enter "Ziegeweid" in the search box.
