gorgeous plates with strange grammar

I recently bought some lovely plates. They are just the right size to serve a salad and their bright decoration makes me feel cheerful. Each one has a message written on it about the uses of olives in cooking.

I wonder if the designer has English as her second language? The messages use language in an off-key way. For instance, here's what it says on the box:

'Olive oil's uses in gastronomy are immense...' 

And one of the plates has this:

'The olives can be green or black and is traditionally served...'

What a pity no one edited the language before the plates were printed. I notice that they were made in China, but they were designed in the USA. Here's the  mark on the reverse of one plate:

I enjoy oddities of language, so I'm expecting to find food served on my lovely new plates has an extra piquancy.

I've found a link to the manufacturer. I think their products are lovely, by the way.
