This thread is almost like a mystery being unraveled by chess-enthusiast sleuths! Nice work @ungewichtet, @brasileirosim, and @marcel_herbst...it really is interesting reading and viewing. I can appreciate that the simplicity has its merits--to weather all the play, transport, and rough handling. No need to sulk over a Q's broken crown or a lost K's finial, yet the pieces are easy enough to tell apart.
Ganz schoen von Ihnen @ungewichtet dass Sie alles so leicht uebersetzen. Sehr historiche sachen in der Zeitung. Mein deutsch ist ein wenig schwach weil ich benuzte es nicht so oefters.
The Grob set seems like a timeless and easy on the eyes minimalist style that works in many settings--a clever design that likely will see an uptick in popularity because of you all's thread.
Well done, cannot wait to learn more!
Nice finding, thanks!
