Another mystery gravestone

Our new member Jon Jacobs has a historical observation and a question regarding the grave of Steinitz, and hopes the members of the CH&LS, or other interested persons, could help him answer this question:
My research collaborator, IM Yury Lapshun, made an interesting discovery when examining and comparing two widely published photos of Steinitz’s grave, and a third photo that we took in 2019 when we visited the grave. The two photos that appear on the CH&LS website (Steinitz, William) and many other websites (copied below), show apparent differences in both the vertical headstone itself, and the wider, ground-level stone on which the vertical headstone rests.
The date of Rubinstein’s death

We received an interesting question concerning the date of the death of Akiba Rubinstein from Mr. Philip Jurgens (Ottawa, Canada):
“[…] I noticed on your following web page: Rubinstein, Akiba K., that you give 15 March 1961 as the date of Rubinstein's death. However, below this information you present photographs of Rubinstein's grave which clearly show 14 March as his date of death. Is there an explanation for the discrepancy?”.
As our member John Donaldson, co-author of the two-volume monography on Rubinstein (The life & games of Akiva Rubinstein, 2nd ed. 2006), is an authoritative expert with regard to the great Polish chess master, I forwarded this question to him:
“[…] As far I can see, remarks of Philip Jurgens are correct. Everybody can see that discrepancy and I wonder why he seems to be the first one who draws attention to this question. Anyhow I couldn’t find an earlier discussion on Rubinstein’s day of death. Wikipedia mentions March 14th, Gaige March 15th. In the 2nd edition of your book on Rubinstein’s ‘chess life’ it seems that you didn’t pay any special attention to the day of his passing away. The picture on p. 424 shows his grave with the illegible date of 14 [-03-1961]. Do you have an explanation for these different dates?”.
Prompty I got his reply from John:

Congratulations on the 85th birthday, Stellan Persson!

On July 1st our senior member Stellan Persson celebrated his 85th birthday.
Stellan became a well-known figure to the Danish chess community during the 25 years he ran Skakhuset in Copenhagen, a classic chess shop of a type hard to find nowadays. New as well as a wealth of antiquarian books often made a visit longer than planned.
Stellan joined Malmö AS only 12 years old when his father brought him to the club. He had a talent for the game and became strong enough to win the club championship in 1955. During his active years Stellan occasionally worked as a chess journalist for various local newspapers. Even if Stellan today shares his life between Gothenburg and Mallorca, his heart is still with Malmö AS whose history he has documented in the book En gyllene epok from 2010. Another historical work by Stellan is a collection of the round tables from the Swedish Chess Congresses from 1939 to 1970.
After closing down Skakhuset in 1998 Stellan has continued dealing with chess material online and also by leading the chess book auctions of SS Manhem, the club in Gothenburg he now belongs to.
Congratulations!
