Subway, Budapest, nose picking

This is an illustration that I just found in an old scans folder.
It was made few years ago while my wife (then still a girlfriend)
and me lived in Budapest.
Well this is kind of how I saw Budapest`s subway.
At that time I didn`t mean that,
but now it looks to me that the couple in the front is us.
Oh, we were soooo young. LOL
