The following is an archived discussion of the DYK nomination of the article below. Please do not modify this page. Subsequent comments should be made on the appropriate discussion page (such as this nomination's talk page, the article's talk page or Wikipedia talk:Did you know), unless there is consensus to re-open the discussion at this page. No further edits should be made to this page.
The article is long enough and new enough. The hook is directly cited and the article is neutral. I assume good faith on the references that I can't access. The image is fine. A QPQ is not needed. SL93 (talk) 23:29, 9 December 2021 (UTC)[reply]
