- load the photo in gimp
- make a copy from the layer
- gimp menu : Filters/Artistic (Mask radius 50 / Percent black 0.025)
- gimp menu : Colours/Desaturate/Desaturate
- rename the desaturated layer 'desaturate'
- copy de desaturated layer
- gimp menu : Colours/Invert (photo becomes white)
- on this layer set layer mode 'Dodge'
- gimp menu : Filters/Blur/Gaussian blur (value 2 - contours appear on the layer)
- gimp menu : Colours/Curves (move point under-left to the right (see picture)

- make new layer from visible (left mouse button - new from visible)
- copy the 'desaturate' named layer
- put this layer under the new from visible layer
- set the layer mode to 'multiply'
Done 

Thanks, denzjos. So many approaches, I have a lot to learn... nothing is straight forward here. Your final output is also VERY GOOD. One question / comment... The background of the original B&W picture needs to be retouched separately wright, I assume is impossible to have everything done in "one pass"?

Thanks for helping.
