KILGORE, Texas (KLTV) - Two vintage televisions have joined the collection at the Texas Broadcast Museum, where founder Chuck Conrad says the museum never knows what it will receive.

One addition is the Dumont Royal Sovereign, which Conrad called the largest black-and-white television ever built.

It has a 30-inch screen, weighs about 500 pounds and cost $1,895 in 1950 - about $23,000 today.
