+1 to most of what Bob and Rhett said. Not only do they come in multiple colors, they come in several shades of each color. The basic colors are red, pink, orange, gold, blue, green, tan (your copy), purple and ivory, again with a multitude of shade variations. While it's largely true that colors command little premium, there are distinct levels of scarcity. Blue and green are the most common; Orange, red and purple the most difficult, with the rest falling in the middle. Even though it's been accepted for years that the colored silks were issued without backs, I'm not entirely convinced. I have seen and owned a few examples with blank cardboard backs. These appear period to me and I don't know why back would be added at a later date. Assuming your Baker has complete captions top and bottom, it's value would be north of $100, depending on soiling, fraying and other considerations mentioned above.
