I have a logo I created in a notebook a few years ago with no date on the page with the logo. The only dates in the notebook are on different pages within the notebook. I also had two photos of the logo however I think that I have lost them as I cannot find them. If a company has the same logo is there anyway that I can prove that I created the logo first, if I was to get a lawyer? Can I do anything or am I out of luck on this one? Any feedback would be great and thank you for your time.
