Morphology
The meaning 'something that no longer exists or is no longer used' is directly derivable from 'thing' (an object/entity) combined with 'of the past' (belonging to or originating in earlier time), so the phrase compositionally means 'a thing from the past' = obsolete. This noun + of + time pattern is common and cross-linguistically transparent, so a B1 learner who knows the constituents will readily infer the intended meaning.
Etymology
A thing of the past paints a picture of a thing put away into the past, like an old tool left on a shelf long ago. That's why it means 'something that no longer exists or is no longer used'.
