Python 3.x undefined name with @staticmethod,@classmethod using 'typing' feature

I've been writing some code in python 3.6 in which the class state can be saved to disk, and then loaded. It goes something along the lines of:

class MyClass(object):
    @staticmethod
    def Load(filename) -> MyClass:
        return MyClass()

print(MyClass.Load('test.pkl'))

When using the typing, I get an error:

Traceback (most recent call last):
  File "tmp/test.py", line 2, in <module>
    class MyClass(object):
  File "tmp/test.py", line 4, in MyClass
    def Load(MyClass, filename) -> MyClass:
NameError: name 'MyClass' is not defined

which suggests that the type name is not available at the time the method is type-checked. However, when actually running the code (when removing the typing) the program proceeds as expected:

>> python tmp/test.py
<__main__.MyClass object at 0x7f249449a550>

The code with typing removed:

class MyClass(object):
    @staticmethod
    def Load(filename):
        return MyClass()

print(MyClass.Load('test.pkl'))

The same error occurs when using the @classmethod decorator. Is there something that I'm missing with respect to the way that the typing feature works? Is there a more "pythonic" way to write this code? (The loading implementation is significantly different from the default constructor, hence the desire to write a different function instead of using keyword arguments).
