[Please help a very, very new guy]

Hi,

I am new to this to a point where I am embarrassed to say how new.  I restore vintage metal and wooden products that have labels, decals, etc that I want to replace the old or missing ones that are from late 1800's to the late 1950's.  Is there a tutorial or information that someone can direct me to that could help me in reproducing the image so I can apply them to decals or labels?   Some of these labels are on a curved object and would taking photos of sections and trying to piece them together work?  Again, flying blind here and any direction would be so much appreciated.

Thanks in advance,

Pat
