Flashcubes - You slid a lever to spin the flash after EACH picture. 4 flashes on each bulb then that was it, you had to pop in another flash cube. No cube? No flash! I can still remember the smell they made after you flashed one.
LP's and I think we had this exact same stereo/record player in my house when I was growing up. My mom would come home with old (when the jukebox man would change the records at work & give her the old ones) and I'd play them on this.
