Old home, is this asbestos in the attic?
I want to preface my answer with this, you cannot definitively say if there is or is not asbestos in a space through a picture, as it requires a microscope. My assumption is based on research and your initial statement about the age of your home as well as personal experience and research.

That said, chances are high that there would be asbestos in there. However, asbestos undisturbed, isn't dangerous on it's own. It becomes dangerous once you disturb it and it is now airborne. So depending on your plans - this may or may not be cause for worry.

At the end of the day - tests are cheap. I just had some testing done last month. In fact most places offer tests for samples you take yourself (they should provide suggestions for safe handling within the instructions). For my testing it was 50CAD for the first sample, and then an extra 25CAD for each additional sample. The turn around was less than 3 business days. 

So if you are really concerned...just get it tested.
