Iterations from a worn-out store-bought wallet to a luxury hand-made version

My wallet wore out about a year ago. I liked the general shape, but was looking for a fun project, so instead of buying a new one I made a similar one, first out of paper, then scrap canvas, then scrap leather, then a final version from Walpier Buttero with edge paint and hand stitching in an accent color. I designed it in Inkscape, and laser-cut the pieces, including the holes for stitching, which allowed me to get very precise stitches. Not pictured - several paper/staples iterations on the pockets tweaking the pattern to my liking

Love it, is the signature on the bottom right laser engraved?
