An Appeal to the Nation (1937) has two foldouts, one at the front and one at the back. The front foldout is printed on both sides, giving three illustrations in all. This booklet has no other illustrations.
In The Druid Temple Explained (1939) Mann used the same three illustrations as in the Appeal, but now on a single foldout, so that two of them had to be reduced.
Besides the foldout, The Druid Temple Explained has four pages of plates in the middle of the booklet, plus a small illustration inside the front cover and a route map on the back cover.
On the plan of the “maze”, the note “64½ ft. diameter” should read “64½ ft. radius”, as is clear from the scale and from other statements in the booklet.
