Salt shaker and pineapple shaped pepper

Adorable little set including a salt shaker and a pepper shaker on a small presentation tray. This set has very nice details, such as the pineapple-shaped glassware that reflects light nicely, the silver metal top whose decoration is in relief (embossing). At the back of the tray, there is a stamp, a capital d crossed by a lightning. It seems to me that it dates from the 70s but without certainty. The set is very small, perfect for placing on a serving tray for example. The whole is in very good condition, no cracks on the glass, no oxidation on the metal, just a few small discreet marks on the tray. The tray measures 9.5 cm by 6.4 cm, the containers measure 4 cm in height and 3.5 cm in maximum diameter. The whole weighs about 80 g.
