@Rubio Re your PI day puzzle: any more hints coming soon? I think i got the final image with the background by reverse image searching, but I don't know how to get there
(the original original image is already mentioned directly in the attributions section, so you can trivially confirm that. note that the actual image I used is somewhat modified; see hint usefulness level 1.)
The C4 is clearlyâ„¢ "establish'd S.E.C." ("response to crash"), which is es (rESuscitate 2nd and 3rd) followed by Tab and L'Ish (victims of the cola wars) all had by D.S.Ec. ("doctor", specifically a doctor of silly economy).
Oh, wait, I was kidding, but it actually works! Securities Act is doctored resuscitate* + 2nd and 3rd letters of vICtims
