The New Columbus Series - Dumas Works

I have six titles in this series. The covers and pages are in poor condition. I purchased them at an estate sale a couple of years ago.

The covers are red with a depiction of 3 palm trees on the front cover(center) and a depiction of Christopher Columbus in the upper right hand corner. The spine is red with "DUMAS WORKS" at the top of the spine imbedded in gold paint. The title of the story is in the center of the spine.

There is no copyright date or date of publication inside.
