I think some of the posters are trying to make this into something it is not. This style is abundant with no markings other than paper labels. All of the early examples I have seen had "Made in China" labels (if they had labels at all). This original poster's example demonstrates that there may also very few cases where someone has tried to add a factory attribution.
Aside from the "Made in China" label, I've seen other labels which are primarily importers paper labels. For example, I've seen them at Corning marked Avita (a known importer of Chinese goods). They don't sell for much, often less than $5 even in shops.
To suggest that this may be made elsewhere, such as Malta, doesn't make a lot of sense to me. We should have other examples from the same factory and none have been found. Actually, I am not even sure why any Malta distributor would go through the trouble of adding their mark. Maybe the mark was added in China as part of the purchase specification.
Alan suggests that his example is pre-1950. I am not sure that can be documented. I've always believed most simple examples with only a flower are later, 1960s or later.
Of course, this is only my opinion.
