For Abercrombie these pieces are gigantic and yet the top one measures 40 x 30 inches and the lower one 15 1/2 x 19 1/2. Abercrombie paintings are usually quite small. The smallest the folks at Richard Norton had seen? One inch by one inch.
The Night Visitor, the folks at Richard Norton believe, may not be the actual, original name of the smaller painting. They have evidence of an earlier name from a late 1940s exhibition at the Art Institute. Abercrombie's work and life remain vaguely mysterious.
The Adler piece (and the others that were on display) were new to the gallery, they had not had pieces by the artist previously.
You can see more of both of these and more at the gallery website linked above.
