manufacturer: Lava Manufacturing Corporation
first production: 1963
comments: This is the Grandaddy of the lava lamps. It's called the Classic Century now because the Century is still in production in gold (as shown) and also in silver and black. The official model number of the Century is the 100. The last two digits describe the color of the lava. So this exact model pictured is the 102. A 103 has white lava in blue liquid. I've never heard what a 101 would be...
Don't you just love it?!
