That would be very long, since some are locked behind others ...Just out of curiostity has anyone wrote a guide for the stamp Collection...
some of them are way Hidden
I can give some tips for them though:
+ At the end of the chapter, pay attention to what has changed in the town cutscene
+ Check around the tower for icons
+ There a stamp locked behind item purchase (the something generator from the shop, the one with "unlimited" or "infinite" in description)
+ Last tip: the change log can be your guide if you can navigate through it efficiently enough
