You wouldn’t want to throw these toys in the playroom bin, even if you had one big enough.

Sotheby’s auction house of New York is brokering the sale of American collector Jerry Green’s 35,000 vintage toys and trains. He hopes that an institution or individual will buy them and donate them to a museum.

Sotheby’s is putting 5,000 pieces on display until the end of the month. The whole collection is valued in the tens of millions of dollars but will not be auctioned.

The toys date from 1850 to 1940 and include rare, handmade and historically significant European pieces. There are replicas of actual train stations, bridges and buildings that were destroyed during both world wars. There are also villages, carousels and Ferris wheels.
