Blue Label Ketchup

[ROBBYBOBBY64]

I believe there are earlier variations too because mine has an earlier date code of 1931. I think the Owen's diamond mark was definitely used in 1929 based on the fact that this style of ketchup top was not commonly used in the late 1930s.

The first screw top catchup was patented by heinz in 1893 and was in use in 1895.
