Early Single-Hole 35mm Film, probably 1895 onwards

Probably Lumière, unmarked, approx. 60 m of 35mm film negative with a single perforation hole, similar in shape to the BH perforation, not round, on each side of the 18 x 24 mm image. - Note: The original negative is uncut and unspliced. It shows two rigid shots/repetitions of actors on a theater stage, typical of early films, in a kind of dungeon set. One part of the negative displays light incidence over about eight frames; another section, about 5 meters long, displays development errors. The image quality of the negative material is surprisingly good, without emulsion diffusion errors in high lights, with typical silver precipitation on the emulsion side, which may also be original and caused by the heavily diluted developers of the period. - A rare document from the dawn of cinematography of historical interest. Probably an internal test by Lumiére, either before the first known films with round perforations or afterwards.

布雷克拍品等级是为了方便竞买人判断拍卖品的成色而设置的。布雷克等级用1到6级来标注外观和功能的成色，(从非常好到非常差)。 在目录图册里用括号里的2个数字来表示，前一个数字表示外观成色的级别，后一个数字表示功能成色的级别。如(3/2)表示外观成色是3(满意的)，功能成色2(好)。 成色 定义参照下列标准： 1 - 非常好 (未使用过，没有使用痕迹) 2 - 好 (新，极少的使用痕迹) 3 - 满意的 (普通的使用痕迹) 4 - 及格的 (明显的使用痕迹，某个非主要部件是后配的) 5 - 有缺陷的 (极明显的使用痕迹, 某个主要部件是后配的，功能上有缺陷，需要修理) 6 - 非常差 (严重破损, 缺少重要部件)
