Hi Claudia,
We made JOHNSON'S® Baby Powder in tins up to 1963. After 1963, the container was plastic. So your tin could be from any date between 1893 and 1963, but without a picture, I couldn't give you any more information. If you e-mail me a picture of your tin, I can get it dated more specifically for you. You can e-mail me through the blog -- just go to the "About the Author" page for the link to the blog's e-mail.
Regards,
Margaret
