Although there is quite an antique industry in tin tea cans that people  kept 
around the house. My own family passed down a double-walled steel tea can  
with Asian art on the exterior that was supposed to hold tea for home  
consumption. Given our religious background, it mostly held skate keys, marbles,  and 
household bric-a-brack. I expect at one time it did contain tea. I am not  
certain of the age, but I would guess 1930s.
