These encyclopedic illustrations of Butterflies and Beetles, are classic plates coming from an old dictionary,
In this case we know the date by which a little of the original publication was still preserved.
The two sheets represent “Lepidópteros de la fauna neotropical” (Lepidoptera of the Neotropical fauna – butterflies) and “Coleópteros exóticos de forma o colorido” (exotic Coleoptera in form or color – insects).
The explanatory text says that the sizes of the illustrations are “a little reduced in size” with respect to the real ones of the bugs.
The frame is included with the illustration, so you can hang it in the moment, wherever you want.
