The Caldecott Collector: Four and Twenty Blackbirds, 1938 Honor: Caldecott and Book Collector Notes

1938 Honor: Four and Twenty Blackbirds: A Collection of Old Nursery Rhymes, illustrated by Robert Lawson; text: selected by Helen Dean Fish. The book was originally published in 1937 by the Frederick A. Stokes Company, which Lippincott acquired during the 1940s.

Collecting? This is what I have been able to extrapolate from inline seller descriptions:

Look for FREDERICK A. STOKES COMPANY (New York) as the publisher. Date: 1937.

GREEN cloth boards with black writing, as pictured below, dustjacket had the main title (Four and Twenty Black-Birds) in LARGE bold red letters, with the subtitle (Old Nursery Rhymes) in smaller green all-caps. Helen Dean Fish's credit is in black ink, Lawson's in green -- exactly as it appears as in my discussion post about the book.
My copy is a second printing, and this is noted on the copyright page with the date November 12, 1937. I would assume subsequent printings are also noted here. The first publication date is listed as October 7, 1937. I was only able to find ONE first printing with enough description on AbeBooks (copy no longer available). The pictures showed a few ID points to help distinguish a first printing:

Price: $1.50. It may be the same on a 2nd or slightly later print; unfortunately, my DJ is price-clipped. Thus, it is possible that my DJ is a bit later than the book. I have no way of really knowing. I am assuming it is also a second until I learn otherwise.
The jacket blurbs on the back inside flap are slightly different on the two printings.

Back inside flap on the FIRST print has the headline "Adventures in Reading," promoting a book by May Lamberton Becker.
Someone must have thought better of the description because the second printing has the headline "First Adventures in Reading: Introducing Children to Books." It promotes the same book, but with much different text. You can see the first edition DJ in detail on Abebooks.

The inside front flap has the same blurb. The picture below shows my second print copy, which is price-clipped. A first should have the price $1.50.
The back of the DJ appears to be the same on both the first and second printings. The headline is: "THE WIDE WORLD IS FREE To Boys and Girls Through Books" with promotions for several other Stokes titles, including:

Adventures of Misha
Pigtails
Melika and her Donkey
Polar Bear Twins
Manga
The Lost Queen of Egypt
A-Going to the Westward
The Secret of the Rosewood Box
Susan Beware!
Summer Comes to Apple Market Street
The Little Warrens at Breezy Hollow

Lippincott also published the book. My 11th printing has RED boards. Mine does not have a DJ. I have found seller descriptions of Lippincott editions that have a DJ similar to the Stokes one except ALL title lettering is in green; there is NO RED on the DJ.
I cannot speak for earlier prints by Lippincott, but there is a noticeable quality and color difference between my two editions. The 11th Lippincott really seems to miss the mark on the green used in the illustrations, resulting in a blotchier and less vibrant product:
There appears to be a first British printing by Hutchinson's Books for Young People (1946). It has ORANGE boards. DJ is much different that U.S.: Green, orange, and black drawing of two children reading under a tree surrounded by blackbirds.

Looking for Lawson? Key works include his 1939 Caldecott Honor Wee Gillis, written by Munro Leaf; his 1941 Caldecott Winner They Were Strong and Good; and his 1936 The Story of Ferdinand, a beloved classic that he also penned with Munro Leaf.
