Syrian Trade Mark Stamp English Pitcher & Flower Vase

Hi all,

This is my first post!  I am sorry to admit that I know little to nothing about the two pieces I am asking about.  I bought them in a small antique shop in the late 90's simply because of the color and stlyle!  I've always been a little curious because of stamping on the bottom.  They seem to be stamped with every kind of stamp I've ever heard referred to.  They appear to be either Porcelain or Ceramic, but I'm no expert and can't really tell.  I have alway's figured they were either part of a mass produced dinnerware pattern or mass produced tourist souvenir set.  

Thanks for any information you might have! :-)
