Harlaco is one of the makers that I have been unable find any information on. The only pieces I've seen with a Harlaco marking are the gigantic lamp-planter combos as shown below.
value: rarity:
At 18" long, this lamp/planter is huge! Yellow glaze is quite uncommon. It appears chartreuse in the photos, but it's actually closer to a lemon yellow. I've also seen this design in pink and in green.
It's the only lamp I've seen that's marked HARLACO. Anyone seen any other Harlaco products?
