Many years ago, I used to post subway posters from a series called "Poetry in Motion."
Then the series was discontinued, and BillyBlog became a barely occasional outlet for me.
However, the series was resurrected in the last few years and I have, on occasion, managed to snap a few photos of the posters.
Here's one I caught on December 1, 2015, most likely on the R train:
The poem is "Heaven" by Patrick Phillips:
It will be the past
and we'll live there together.
Not as it was to live
but as it is remembered.
It will be the past.
We'll all go back together.
Everyone we ever loved,
and lost, and must remember.
It will be the past,
And it will last forever.
