This is a vintage Genuine Onyx Imported Perpetual Calendar with Swivel Pen Holder by New Diamond.  It has the original label still affixed to the front right corner (some wear to the edges).  The onyx is in excellent condition with no chips or cracks.  The brass casing on the calendar has some age-appropriate spotting which may be able to be polished off -- we are selling it in as found condition.  The date numbers and months are perfect with no discoloration.  Three days of the week -- Wed, Thu, & Fri have some foxing beneath the day which are mostly concealed when the day is in the window (see photos).  All in all it is a great vintage piece and totally functional!  Bottom is lined in green felt.  The onyx base measures 6-1/4" x 2-1/4" x 7/8" high.  It is 2-3/4" high to top of calendar (not counting the pen holder).

NOTE:  Pen in picture is not included and is only to show how it looks with a pen in the holder.
