You know, I started hating the fact of not being noted, when I found out more than 30 works, and for the most stuff put on sale, in a period when I didn't let yet.. and it made me feel kinda frustrated.
I understand your annoyance, I would also like to be me. I always notice to the owners so I put the art, but this time I was absent and did not have the time to come to warn you.
Happens to me too, I see people using my stock and I never give news. I apologize once again, I do not practice it. If you notice, I have many years in the DA and nobody ever complained to me, because I always have been correct with the use of stocks.
