[Man at a Sulfur Mine]

Description: Black and white photograph of an unidentified man wearing a suit and a hat, standing amidst a massive pile of mineral rocks at a sulfur mine. He is holding a rock in his hands and observing it. A handwritten inscription on the back reads: "Hoiskoleforstander A. Gronborg foran et Svovlbjerg ved Gulf Svovlmine." An online translation endeavor provided a few potential conclusions: that the man in the picture has the name A. Gronborg and that he is indeed standing by a sulphur mine in the gulf (presumably in Texas). The only established Texan city in Wharton County with a sulphur mine is Newgulf, Texas.
