Carnival Glass Imperial bowl = Pansy Pattern

I fell in love with this Carnival Glass bowl, that my friend on the market was just putting out, so I bought it, despite the rather pricey tag. It's a lovely bluey yellow colour, until you hold it up to the light, when its a lovely purple pink. I think it is from the Imperial Glass Company, though I am sure Tallcakes knows all about it? The man on market loved this bowl, but doesn't like marigold carnival glass, so he just puts it in his £1 section, and he produced a Dugan Marigold bonbon dish (with a chip on the foot) which I bought for a £1.
