The first is a real odd-ball. Dear Sir; by Juliet Lowell was a collection of letters written my Americans during WWII. It was published in the US in 1944 in hardcover and paperback. Then, as S4, by Collins in 1945. It is described on the front cover as "A White Circle Pocket Edition" and has ads for other White Circles. But the publisher is North Star which was an imprint of Collins (see post of October 22). Collins isn't mentioned in the book. Collins also published Dear Sir; as a hardback without any reference to White Circle on the front cover.
Below is the White Circle edition and the American paperback edition published by Eagle Books of New York.
The second odd-ball is Harvest Triumphant by Merrill Denison, published in 1949 as a paperback original. This book is described as a White Circle on the cover and inside. The title and copyright pages are identical to other 1949 White Circles in the numbered series. The only difference is the book is not numbered. There is an interesting connection, perhaps coincidental, with the numbered series. The only other Denison White Circle is 431, Klondike Mike, published in 1949 as well. White Circle 430 does not exist. Perhaps Harvest Triumphant was intended to be 430 but the number removed before publishing.
