Set of Five 2 Inch Square Stone Blocks New York history but I for the life

but I for the life of me can't figure out quite what this one is

If not enjoyed just as is

I see them as just gorgeous sculptural objects

My guess might be 1940s or so

Set of Five 2 Inch Square Stone Blocks New York history but I for the lifeThese came from the studio of artist Richard Fleischner, and in that context especially I found them really beautiful, stacked in a group and looking very much like a minimalist sculpture. I believe they are probably limestone, and of a satisfying scale, and if not just arranged unto themselves would also make very good pedestals for other things. Set of 5, all in good condition, with minor edge wear. Each measures 2" x 2" x 2" and weighs 10. 6 oz.
