At first glance they look like different signatures, but if you look at the way each letter is written, you can tell it’s most likely by the same person. RHB. For me personally, my signature has different styles (so to say) depending on how lazy I feel, rushed, you know...
The signature is scaled and slanted in the second one to fit the box, the pattern is similar when you account for that. You can apply a scaling function to the one sample to aproximate the other. I'm not a forgery expert, but have done research on pattern recognition when I did my Computer Science PhD dissertation on AI automation.
If you can calculate a function that makes one image change to resemble another image, that's evidence the images may be from the same source.
At what letters exactly?
Specifically look at the loops and structure of the R, H, and B.

Specifically the H. Looks like a sloppy star near the middle.
