(Freehand) Line and Form: 1880s Pennsylvania German Ink Drawing of Cabin with Conical Roof and Perfect Picket Fence

I know this ink drawing dates to right around 1880, and came from a ledger held by a young Burt Gemberling of 

Selinsgrove, Snyder County, PA who also drew the portrait of the Native American chief listed today. I love a painstakingly rendered portrait of an architectural structure in this manner, attention given to every beam and, best of all here, to each post of the picket fence to either side. Looking closely, none of the very straight looking lines is actually perfectly straight, such that I don't believe a ruler/straight edge was employed in the making of this. 

12 7/8" x 7 3/4". Excellent condition, black ink on laid paper, with a folded over top edge of the paper.
