They should be posting the info soon on their site. BTW anybody who is wondering it is Photo Fest. A very respected photography show in Houston.
The only problem I would see with a coop would be the quality of work and the types of work. If you are the only photographer then people who visit the gallery might be used to seeing paintings, sculpture etc dont know if that is good for you or not, but I would rather have my work where people know they go look at photography.
The traveling firm thing, well if Clyde Butcher uses them, they gotta be good. Who know what their requirements are?
