System.ArgumentException HResult = 0x80070057 Message = Parameter is not valid. Source = System.Drawing. Why?

Using c#, I have extracted a cursor resource from a PE file and removed the x-y hotspots and prepended the BITMAPFILEHEADER but when I try to convert to a BITMAP for display in a Picture Box as pbResImage.Image = Image.FromStream(bitmapStream.BaseStream); I receive an argument exception.

My code works for dozens of cursors and the cursor in question is extractable using other programs.

I believe the simplest approach is to examine the actual inputs to both by code (bitmapBytes) and to the stream passed to Image.FromStream (bitmapStream). I have tried and tried with no success.

I am asking your help in examining the inputs and identifying what is ACTUALLY INVALID about bitmapStream. Once I know what .NET is finding faulty, a solution will probably be at hand.

Here is the bitmapBytes array that I extracted:
