davidcyclebackI agree, that's about as large as an early 1900s baseball photo gets. The size alone makes it rare. Plus, the ornate frame is unique. No question it would make quite the display piece on the wall.
For 1800s-early 1900s photos, 20x20 inches (sometimes a bit smaller) and above are often referred to as mammoth. As this photo is even larger than 20x20 inches, it can definitely be labeled as mammoth. As the name implies, mammoth is applied to photos that were really, really big for the day. Mammoth is really just an official nickname.
With old photos, if the collector uses the wrong term (cabinet card, imperial, mammoth) but gives the dimensions, the knowledgeable buyer will know know what he is talking about.
