(e) Twinkletown Houses
Perhaps the best known H&H accessory is the series of five tinplate houses, each house measuring 4 by 5 by 3.5 inches high, excluding the chimney. Five combinations were issued, all with a white chimney and a tab for internal lighting. All were supplied flat, for the purchaser to bend along pre formed creases, then assemble using tabs and slots. All were supplied with a bulb and fitting for internal lighting, and a suitable tab.
