Accordion Pleated Pitcher (Germany)

This pitcher was bought in an antique shop in Ontario, Canada. It's a tall pitcher with an accordian pleated surface and a sharply angled handle. The colours are turquoise, black and white. I'm not sure if the item is china or porcelain (I'm thinking china). I have searched all over the internet for anything resembling this item and found nothing. The closest was a deep pleated white bowl. Nothing with the unique painted finish...nothing even close. There is a stamp under the glaze on the bottom that simply reads "Germany" with the "G" being fancier and appearing doubled although that may simply be the font they used. Another forum suggested that the pitcher might be from the 1950's and have been manufactured for export, although that would lead me to assume that there were many made and yet I can find nothing similar on the internet. Hopefully someone will recognize the item and be able to tell me something about it and perhaps the value of it.

Thanks for your help!
