These are obviously called E97, but we really don't know if they're a candy issue.
I would guess they weren't inserted into any product.
They're really fragile and I haven't seen them with any kind of candy stains.
I would guess a very small firm used them as some kind of premium or give away. I say very small firm cuz they cut corners on the paper stock and decided to go with no color which was probably a lot cheaper.
In fact, as Scott hinted at, perhaps there was an excess of cards that didn't have color or backs printed yet after Briggs decided to stop using them and whoever had the stock decided to sell them to a local store/company. That would make slightly more sense if the stock was the same thickness however.
Several of the images were also used for W555.
