Puzzeled

I am puzzeled by the fact that once an artist has an exhibiton on the walls, they stop promoting the exhibition.
Dang !!! Once I get my show open, I don't stop promoting the event until ,the event is over.
I go into co-op galleries and often the artists are waiting for people to come in.
I would send out , real mail, to invite people one more time, to come for a chat or visit.
Most times after the opening, the artists sit on weekends to empty galleries.
I would consider ,offering some kind of incentive, to get people in before the show closes.
Hey, marketing matters, if one wants to get paid.
