The triangular plates have a moulded recessed imprerion that fits the serving cups. This is a matching set that still has the accommodating condiments/sugar bowl.
There are a few micro flea chips in the orange glaze here and there as you would expect and a shale chip in the clear glaze on the bottom of one of the plates (Pictured). Overall the set is in wonderfull condition having spent circa 80 plus years in circulation, most of that most likely in a curio.
These are antique and not perfect but extremely nice. Serve your company with extreme style, these are sure to take over the conversation's everytime. Plates are approximately 8 3/4 diameter. The set/design is titled " Streamline " made by the Salem Co, Made in the U.Please enjoy all photos using zoom.
