>>7840435Here's my shot at it
Because of the heavy film-grain like texture, I used a technique called frequency separation to be able to edit the texture of the picture without having to deal with colors. How you actually do this is different between different editing suites/softwares, so I can only explain for GIMP (just google for whatever software you use).
In short: you duplicate the image layer, and set the layer mode (at the top of the layer panel) to "grain extract". Nothing changes until you blur the new layer with a Gaussian blur (under filters->blur->Gaussian blur). I use around 6.5, but all you need to know is that the more you blur, the more extreme the texture becomes. After that, right click the layer, choose "New from Visible". Set the current layer (now the low frequency layer) mode back to "normal" and the new layer (now the high frequency layer) to "grain merge". If everything went right, the image should look like the original. Now if you hide the first layer you made, it should look gray but sharp and the other way around it should just look blurry.
After that, just paste it till you make it. The clone brush and the heal tool are your friends here. Just remove the text on both layers. On the high frequency layer it will be actually removing the text itself by pasting the texture around the letters over the letters. On the low frequency layer, it will more more like hiding the color of the text and replacing it with what the blurred colors should look like.
I made this sped up video of me doing the edit on your image that you can watch here:
