Should paintings be signed?
The simple answer is you should sign your first painting or piece of art and continue from there. Your signature is your brand, your mark of ownership. It identifies your artistic work as your own original.
Should you sign and date artwork?
If you are not expecting to ever be a great artist dont date the front of your work because normal people who buy paintings just to make their room look nice prefer things that are fresh to the market.
