Hi,
I have found this sentence: “Hey, there, where did you find a picture of me old specs?”
However, I am asking myself why it shouldn’t have been written as follows:
Hey, there, where did you find a picture of my old specs?
Hey, there, where did you find the picture of my old specs?
“me old specs” is just an old form, or perhaps a rustic form of the language. The correct form is “my old specs”. As to “the” versus "a’, this depends on whether the reference is to “a” picture (one of many) or “the” picture, that particular one, or perhaps the only one in existence.
