Support – good EV in its article, well preserved, The scan resolution is 150 pixels per inch (per the scale on the map), and all is legible when enlarged (say at 200%). I updated the source links. Bammesk (talk) 15:31, 12 October 2024 (UTC)
I wasn't aware of the other two maps. One of them is older, it dates to 1918. The settlement regime ended around 1942. The nominated map dates to approximately 1935 (per the map itself, although it's a 1945 print), so the nom map is the most recent of the three. I like the bilingual annotations on This map, but the problem I see is that its legends are in Chinese only (not readily legible in an en-Wiki article). Also the nom map is in the article since 2012, whereas the other two maps aren't. Bammesk (talk) 00:59, 15 October 2024 (UTC)
Stability is a fair point, though given that the two I linked above were uploaded this year (though other versions saved at higher compression are older) it's to be expected. Hmmm... given the dynamic construction of Shanghai in the early 20th century, the seventeen years between the 1918 map and the 1935 map nominated here could be significant.
