This could be a good way to make a "paint tent" to use the sprayer in at the shop? Maybe just with heavy plastic & duct tape so it can be changed when it gets bad? Basic Market Stall, would also be a lovely shaded area for hot events!
An a-frame with the merchanting style side-panel door. I don't believe there's any authenticity argument for this set-up, but it sure is convenient. This particular tent doesn't even appear to have traditional door panels.
