While there are not that many, I have a few geckos to contribute...
Eublepharis macularius Blyth, 1854; Leopard Gecko. Yujin Lizard Pictorial Book 2002. It's the same sculpt as the PV version sbell posted further above.
Goniurosaurus kuroiwae (Namiye, 1912); Kuroiwa's Ground Gecko. Yujin Lizard Pictorial Book 2002. This is apparently an alternate paint version of the figure sauroid posted
here.

Hemidactylus frenatus Schlegel, 1836; Common House Gecko. Yujin Lizard Pictorial Book 2002. Possibly the same sculpt as the PV "Panther Gecko" sbell posted above.
