Legendary Auctions is currently offering up for auction 800+ items from the Bill Mastro collection. Mastro, who use to run Mastro Auctions before it imploded, has one of the more extensive and coveted collections in the hobby so I imagine there is a great amount of interest in what they have to offer. Included are numerous 19th century rarities and game-used items from Hall of famers. There are also a good number of Dodger related items worth a strong look by collectors. Below is one of those items.
Here is a vintage souvenir mirror, measuring 2.75" horizontally, made in 1910 featuring Ebbets Field. Likely sold at the stadium this example is very rare.
