Here are two books
written by IK Marvel (pseudonym of
Donald Grant Mitchell) which have the same format. They undoubtedly
belong to the same series but which one is unclear. Both books have
1893 on the title page. The question is whether they belong to the Altemus
Library (Series #37) or the Famous
Red and White Series (Series #85) or are part of another series.
The books have the same spine as is seen in the Famous Red and White
Series. But the two 1893 titles already in this series have been seen
and have different covers.
The Altemus Library books with these titles have different covers. The
characteristic of this series is that all the titles had different
covers. But some titles did have more than one cover and it is possible
that these titles fit into that category. I suspect that this is the
case but I cannot prove it.
