[Retros] A request to find a problem

[afretro]

Dear colleagues,
I remember seeing once a problem (probably a helpmate) in which both sides could make an e.p. capture immediately when being on the move. I.e., if black is on the move, he can play 1.e.p.; if white is on the move, he can do the same. I could not find it in the PDB database, but perhaps I am a bad searcher. Can anyone help me find the position?
Yours,
Andrey Frolkin
