Usage outdoor museumbuildings signs

See Kaplansloftet, Skansen (Q60224753) were I use plaque image (P1801) for signs telling abut the usage of the building. Ok? - Salgo60 (talk) 15:38, 15 January 2019 (UTC)

Sounds OK to me, the item is the main topic of that plaque. Syced (talk) 05:43, 4 September 2023 (UTC)

It is wrong. Create an item for the plaque and tell what it is about. Works about something should always have their own item. Asterix2023 (talk) 17:57, 31 October 2023 (UTC)

Multiplicity

Albert Einstein (Q937) (mis?)uses this property as a "pictures gallery" of all plaques that have ever been built about the famous scientist. I feel like we should have one plaque as a property, and a "Plaques Commons category" containing all plaques. What do you think? Syced (talk) 05:41, 4 September 2023 (UTC)

There should be an item for each plaque, images can be stored there. And there it can be stated what the plaque is for. Asterix2023 (talk) 17:54, 31 October 2023 (UTC)

War memorial doesn't conflict

This entry doesn't conflict with WAR MEMORIAL because a war memorial can be something other than a plaque. - Chris.sherlock2 (talk) 11:23, 16 March 2024 (UTC)
