How to use Reflection to read Static Properties from a Nested Class?

I have some configuration stored in the following data structure which uses nested classes for Organization.

public abstract class LogoSpec
{
    public abstract byte[] Logo { get; set; }

    public class Web
    {
        public static float Width { get; set; }
        public static float Height { get; set; }

        public class A4 : Web
        {
            public static float Left { get; set; }
            public static float Top { get; set; }
        }

        public class Letter : Web
        {
            public static float Left { get; set; }
            public static float Top { get; set; }
        }
    }

    public class Print
    {
        public static float Width { get; set; }
        public static float Height { get; set; }

        public class A4 : Print
        {
            public static float Left { get; set; }
            public static float Top { get; set; }
        }

        public class Letter : Print
        {
            public static float Left { get; set; }
            public static float Top { get; set; }
        }
    }
}

public class SampleLogo : LogoSpec
{
    public override byte[] Logo { get; set; }
}

I can easily use it when I exactly know what value to use at design time

// Usage
SampleLogo.Web.A4.Height = 10.25f;

How can I retrieve these values on runtime using reflection?
