Q. I bought a collection of old children’s blocks at an estate sale. They have pictures of animals and the alphabet on them. Much of the writing is worn off, but some have rhymes on them. A couple blocks are missing a side. I think they are charming but are they trash or treasure?

A. These types of blocks were popular in the late 1880’s. At that time there were close to two hundred game and toy manufacturers in the United States. The better quality blocks were made in wood with lithographed paper decorations. The higher quality blocks were primarily made by Singer, Converse and McLoughlin Brothers. Their blocks are desired for their detail, colors and graphic appeal. These companies were primarily publishers of children’s books.The blocks evolved from already having the colored printing technology in house. They also made games and paper dolls. At one time, McLoughlin Brothers was the largest toy manufacturer in the United States (until 1920, when they were bought by Milton Bradley of Springfield, Massachusetts).

Many of the illustrators for the books and blocks became somewhat famous. These include Thomas Nast who became a famous political cartoonist, Palmer Cox who did all of the cartoons for the Kodak Brownie Camera and Ida Waugh who became famous for her paintings and illustrations of babies and children. Blocks with images done by famous illustrators are more desirable.

I cannot tell from your photograph who is the manufacturer of your blocks but a set of nine blocks that survive to this day in good condition is rare. Remember, these were toys that were played with by children. Even though they are made of wood, they cannot withstand too much weight or pressure. If not kept in a moderate environment, the paper can get moldy or fall off. Comparable sets in similar condition sell mostly for around $200 and up.
