13 Color Volumes with Color Photographs Printed Using the Miethe

Carl Weller Verlag, Berlin. Large-format volumes measuring 37 x 28 cm, the color images mostly measuring 15 x 19 cm, individually mounted on black cardboard measuring 37 x 27 cm. The color plates are complete and, after approx. 100 years, demonstrate the excellent aging stability of the original printing ink – without fading, color casts, or even altered shadows (due to diffusion into the paper), as can occur with some modern printing inks after 20–30 years of storage. Some of the covers or cardboard backings show signs of aging, but not the photographs! The colors are in very good condition. – All book titles are in German; see the German catalog text for details.

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)
