This old radio

A knob on an old Crosley radio, handled in the distant past by someone with paint on their fingertips, with only some of the dust normally residing there. For scale: the knob is a bit less than an inch across.

 

Processing note: This camera needs noise reduction. I used DXO prime. Toning and vignetting via Color Efex (Film Efex vintage 07 - saturated fade preset).
