Balmer, Philip - When Worlds Collide & After Worlds Collide

Two volumes in one. Grey cloth, blue lettering. A US first edition thus (?) - 1932, 1933 stated on copyright page, but given that After Worlds Collide was first published in 1944 this cannot be the publication date for this book. I have seen 1951 given as the publication date.

WRAPPER : The wrapper on this copy is bright, unfaded, clean and unclipped. It shows light rubbing to the upper edges and to the leading edge of the front panel. Looks sharp.

BOOK : The book is square and tight. The boards are clean and sharp. The corners are sharp. The pages are very clean. No foxing. The closed page edges are unmarked. No dog-eared pages. The hinges are intact. There are no previous ownership inscriptions. A good looking copy.

Publisher: J B Lippincott, 1951

Condition: Near Fine. Wrapper: Very Good ++
