Sonia’s amateur journalism The Rainbow, Vol. 2 No. II (1922), now on Archive.org as an excellent scan. With fine pictures of Mrs. Miniter, Morton, Loveman, Lilian Middleton (S. Lilian McMullen), and a picture of a young Moe that I had never seen before. Plus “Celephias” by one H.P. Lovecraft.
No. 1 was reprinted as a facsimile, but No. 2 has never been widely available until now.
Deep Cuts has a new long post on The Rainbow.
