I cant find any information on it, and would also like to share some of my finds with this community. It is A triangle shaped bottle (3 sided) and the cap is sealed on real tight. It says triangle catsup from wheeling west Virgina, USA.
Welcome to the forums. Can't tell you anything specific about your bottle, there are many such small company, label only product bottles out there. It appears to be early 20th century in age. Jim
