Is this property needed?
[edit]Wouldn't someworkinscription (P1684)somesignature
- That seems to be fairly rare and would require an additional qualifier to ensure that it's actually the signature. --- Jura 18:12, 30 October 2019 (UTC)

Try it! Sample image for the second query: image (see bottom right corner).
- Items used: visual artist (Q3391743)
- Properties used: occupation (P106) , subclass of (P279) , given name (P735) , family name (P734)
# completeness P735/P734 for visual artists
SELECT
(COUNT(DISTINCT ?item) as ?all)
(COUNT(DISTINCT ?hasP735) as ?P735)
(COUNT(DISTINCT ?hasP734) as ?P734)
WHERE
{
?item wdt:P106/wdt:P279* wd:Q3391743 .
hint:Prior hint:gearing "forward".
OPTIONAL { ?item wdt:P735 [] . BIND(?item as ?hasP735) }
OPTIONAL { ?item wdt:P734 [] . BIND(?item as ?hasP734) }
}
There queries require:
- an item for the artist.
- item has P569 and P570
- item has P735 and P734
- ideally a P109 statement

this seems to be presenting a result, feel free to remove the disk after everything is cleared. I do not use creator's signature (P7457) for the artist, but think the description reserves it for the artwork. Which is a pity, as I feel it would be perfectly ok, to use it also for the artist (I have started c:Signatures of artists from Austria). And, your solution does not care for unknown dates of birth and artists still living. --Herzi Pinki (talk) 18:14, 2 January 2021 (UTC)
