I was notified by a colleague that GM Evgeny Postny added to his social a media a photo he took of Emanuel Lasker's grave. It is reproduce above.
It should be noted that the graves of many chess masters are found in the somewhat morbid but fascinating web site, "Find a Grave." These include among many others the graves of Steinitz, Lasker, Capablanca, Alekhine, Botvinnik, Tal, and many others.
