Here's one from the history books!
Not exactly a Cocktail Drum but certainly in the spirit of quirky and portable. Found it on ebay. Here is a partial list of the contents:
Wooden case 20" x 12" x 4.5"
Sticks 14”
Wood Block ( called Chinese Clog Box) 5.75" x 2.25" X 1" Clips on BD
Wood Block 6" x 1 .75" probably not original
Snare Drum 6.25" x 2" - clips on BD double headed with snare
Side Drum (Tom Tom?) 6.25" x 1.25" Single head
Siren - working but feeble!
Swannee whistle - working but tiny
6” Brass cymbal with hanger
5” brass cymbal with hanger
5.5” triangle
4” triangle
Triangle beater
T arm in two parts to suspend cymbals - clips on BD
BD 10.5" x 3.5"
It seemed to be a novelty item for kids but probably somewhat functional for the day...
