LA Bantam - Enter the G-Men

The 9th book published by Bantam Publications is Enter the G-Men by William Engle. The book is subtitled "Johnny Barton Pitted Against 'Monk the Fiend'". Engle published three G-Men novels in the 1930s, one under Engle and two as Laurence Dwight Smith. This is a paperback original.

In common with all but one of LA Bantam's books Enter the G-Men is 100 pages long and is 110 mm (4 5/16") wide by 152 mm (6") tall. Cover and pages are made from high acid pulp paper. The page collation is:

[1] title page,
2-100 Enter the G-Men.

The title page has the copyright date - 1940.

In common with most LA Bantams there are variant covers. The three I know of are strong yellowish green/light orange yellow, strong yellowish green/light yellowish green and strong blue/light orange yellow.
