New on Archive.org, a scan of the 1937 Not At Night Omnibus. This had Lovecraft between hard covers, if only in the British Isles. In the form of his “Pickman’s Model”, and the revision tale “The Horror in the Museum”.

Weird Tales offered their most suitable grue-some stories, these being selected by the magazine’s London agent Charles Lovell. The Selwyn & Blount anthologist Christine Campbell Thomson then made the final selection and ordering for the chunky mass-market hardback. One might have thought it would appear for Halloween in the autumn lists, but it appears to have been published in April or May 1937.
