Oenskynlik lyk Preller se "Morning Glory" na 'n tradisionele stillewe. Formeel en ikonografies gesien is daar egter begripsmatige inkonsekwensies in die werk wat slegs struktureel-simbolies verstaan kan word.
Seemingly Preller's Morning Glory appears to be a traditional still-life. However, ordinary formal analysis and iconographic description lead to inconsequences in the representation, which can only be resolved through a structural-symbolic interpretation.
