 Participation in visual games of make-believe using pictures as props is a complex perceptual and imaginative activity. […] At a minimum, one imagines seeing the depicted objects or objects of the kinds that are depicted, as one scans the picture surface. One also imagines one’s actual visual experience of the picture to be a visual experience of these objects or objects of these kinds. […] I claim that this complex experience constitutes, approximately, what Wollheim and others call seeing trees, fields, etc. in the picture. (Walton 2011: 396–397)
