I had two choices for this particular theme. It was either A) go by the literal meaning of the word Pop Culture, or B) go even more literal. So I decided to go with the latter option.
In this photo you will see that there are two subjects: the Can and the Flag. This was taken during Canada Day where we celebrated and had a mini picnic of sorts. Coincidentally, this photo I took exactly is Pop (as in the can of soda/pop) and Culture (the mini Canadian flag).
So I guess this photo saves the day.
