Hey everyone, I want some help related to my sibling's history project about Goa.

So, basically she was told to make a documentary on the topic "Amche Vintage Goa in 1900s" and she don't know where will she get images, it should be between 1910s - 1960s of some places in Goa which are not available on google. Can anyone suggest from where to collect this pictures from? (Specially photographs which are original and related to the freedom struggle) Please provide information of any website of you know, it would be great help.
