The Foundation for the Preservation of jewish Heritage in Poland reports that roughly 80 tombstones, with their vivid polychrome decoration fully intact, were discovered in the Polish city of Radom during road construction work.
This is an extremely valuable find -- although tombstones with remnants of painted decoration still stand in some places (notably in Radauti and other towns in northern Romania), few show such well preserved painting. (See photos I have posted of some of there by clicking here.)
The Foundation and local conservators are working to preserve the stones, which have been moved to the Radom Jewish cemetery.
You can view pictures of the painted tombstones here.
