Otherwise, I paint solely for my own enjoyment and have never seen a need to sign them. There are only hundreds of pieces- not thousands. Now I print my full name with a signature of Kathy above. I date it on the back in pencil with a short note about the inspiration for the painting. Even as technologies progress, between each transition is a period where you can transpose your older works into the newer formats of archiving.

Signing and dating
Personally I find signatures on paintings to be obtrusive and intrusive to the process of immersion in considering the impact of the work. Dendrochronology refers to the scientific method of dating wood, using the presence of tree rings. My composition is the painting, my name is on the back of the panel, and then on the backing of the frame. People respect inventory numbers because it shows them you are a serious painter and may have painted at least one other painting. To not have a legible signature and date is a restoration artist nightmare. Any additional thoughts or advice? From the shop keepers point of view knowing the date can stop you accepting works for sale that have been shopped from gallery to gallery and not sold.
