I would appreciate opinions on this SP of Jon Pertwee as Worzel Gummidge.  The photo is postcard-size and has a shiny surface.  The image is low-res, dot-printed.

The ink appears to be on the surface and cross-overs are visible but I wonder if it is handwritten or produced by machine.  I examined the image using a hand-held microscope and some pictures are shown here.

If there are any experts here in handwritten vs printed signatures I would appreciate your input.

Thank you.
