Created on black "scratch paper", which comes in a pack of five sheets (plus tool) for $4.00 from a toy shop.
Oil pastel resist and watercolour wash on wet watercolour paper, with black Sharpie silhouettes and gold metallic Sharpie sparks on the sparkler.
This is how my brothers and I spent several Cracker Nights in the 60s and 70s. We had no awareness that we couldn't always afford to have fireworks bought for us, so we pressed our noses against the back screen door. Or had sparklers and a few throw-downs only, if we were lucky. (Or got invited to next door's bonfire if we were *really* lucky.)
