Collecting Early Machine-Made Marbles: The M. F. Christensen & Son Company and Christensen Agate Company

Keeper

Robert Block's books are among the best references for marble collectors. The illustrations are profuse, and the color reproduction is excellent quality.

What I liked about this book was the many photos of the different marbles through the years, the main dislikes were some of the photos were faded and the pricing was not up to date with the times. Overall, I enjoyed matching several of the marbles from my collection to those found in the book.

The Block family are true marble gurus. They make learning all about the addicting glass balls easy.

A vary good book too have on your shelf. I enjoyed vary much and was helpful and I use it a lot

Both of the books I purchased from Amazon [Marble Mania and collecting early machine marbles] are great and helpful addition to my marble collecting.Thank You very much sphere
