I posted something similar to this, but wanted to post again, because the question is a bit different and I wanted to get more replies.
Do you sign the front of your prints - whether they be paper prints or canvas, etc? I am likely going to include an informational label on the back of my sold prints as well - my printed name, company name, title & subject location information. If you do not sign the front, would you sign the back - and, if you do sign the back, is that considered more acceptable, because signing the front might be considered “ruining” the print? I found a lab that will do any or all of the above for me, but was wanting to tap into others’ experience on this matter.
