Abstract
A holder for fireworks comprising a pair of rigid uprights of sheet material and a number of rigid plates or shelves of sheet material extending between the uprights. Slots in the respective components provide for assembly into a self-supporting fireworks holder by the relative telescoping of the uprights through the slots. Legs of sheet construction are also telescoped through slots in the upright and interlock with slits in the baseplate to rigidify the structure. Holes in some of the plates hold the fireworks in position for firing. The baseplate is substantially free of holes to serve as a shield to prevent inadvertent ignition of materials proximal to the holder.
