B. N. Morris

This is one of a series of undated Morris catalogs that share the same cover graphic, but differ in colors. Careful analysis of these catalogs suggest this is the middle of three, being preceded by the catalog with a red-on-red cover and followed by the catalog with a green-on-yellow cover. 

The date estimate is based on comparison with catalogs that are dated, and this catalog's position among the three undated catalogs.
