A chrome plated extra large travel cocktail set in the original leather snap stud case. This is a very rare sized example of these popular travel sets.  There were many different iterations of what came neatly contained in the larger, usually cocktail shakers.  This set starts with a large Thermos style bottle, that is also the cocktail shaker, with lemon squeeze on the inside of the lid.  This will keep liquids cool, or hot, depending on preference.  Next up are fie stacking cocktail shots.  There is a bottle opener.  At the bottom is a screw top glass bottle for either mixers or spirits.  

The whole piece was made in Germany in the 1920's.  Marked on the base D.R.G.M.  The acronym, with or without punctuation, stands for Deutsches Reichsgebrauchsmuster, meaning that the design or function of an item was officially registered inside all of the German states and not only locally registered as it was the case before the introduction of centralized registration.  In excellent, unused condition.
