I bring you the most faithful version of the Batman logo from the 1989 movie starring Michael Keaton. It's the logo that appears as the Bat-signal and also on the movie poster.
It's practically a perfect copy. I also added two holes of approximately 10mm by 1mm on the black base so you can attach a neodymium magnets.
Here's the link:

I also created the logo for the costume that goes on the chest, it's 99.9% identical to the original.

It took me a lot of time and effort, I hope you enjoy it, and if you have any suggestions, please leave them in the comments.
