I was curious to know how a missing person might have been looked for in the 19th century or early 20th century - 1890s-1930s - as they didn’t have things like news broadcasts and such. Any ideas?
Until tech evolved enough, there were 3 basic methods:
community word spreading (like talking about it in public locations like bars, etc)
local newspaper articles (missing announcement posted there)
local posters (posters on building walls and specially where many people were present, like markets)
