Trustgallery exhibits a couple of pieces at a time, in unexpected places, on random days.  

Some pieces will be found, some will be taken, some will be paid for, some will be damaged or lost, some will be kept and treasured.   

If you have found a drawing or painting, feel free to send an email or a quick photo to trustgallery(at)gmail(dot)com, so it can be archived as 'found.'  

If you really like the piece and intend to keep it, pay as you wish through google wallet or paypal.
