Antique Vintage Drinking Glass + Sterling Cup/Shotglass + Metal/Glass Flask

Description

I purchased each of these items separately in various Wisconsin antique stores over the past 10 years.  They have the common theme of 'antique drinking utensils'; therefore I am offering them together in this  lot.  I believe they date from the late 1800s to the early 1900s.  Offered are the following old items:
1.  Sterling silver folding cup/shotglass which easily collapses.   It is 2 inches tall when pulled out fully.   Around the top shining outside sterling silver it appears to be enscribed "Davis 550 Prospect Place, Cincinnati O".  On the bottom it is marked "Sterling". I comes with its original leather case.
2.  A drinking glass that is stored in its original leather covered case.  The glass is in good shape with no chips.  The leather case has scuff marks in many places and a few small areas where the leather has torn away.  The glass is 2.75 inches tall.
3.  A glass flask that has a metal top (with cork inside top) and a removeable metal bottom protective piece.  It stands approximately 5 inches tall and is fairly weighty for its size.
