To my knowledge, the only image which could be made of Bonnie Parker along with Frank Hamer in the same phpto, would be a still created from Ted Hinton's film shot after the ambush. In some of this footage, Hamer can be seen watching as Henderson Jordan scours through B&C belongings from the death car. Of course within these moving images, B&C can be seen dead within the Warren car. It would likely take a review of all the Hinton footage, to see if a good photo of Hamer & Bonnie together would be possible. If you proceed to Hinton's footage blog right>> I recall there's a scene with Hamer visible, where the camera pans away from B&C to view Jordan and Hamer behind them. I believe that scene could be freeze framed to include both Hamer and Bonnie.
Frank Hamer is not known to have ever seen Bonnie Parker or Clyde Barrow, prior to the ambush. There do exist photos shot from the doorway of Congers, with Hamer visible at Bonnie's door seemingly made before the bodies were removed. However in both a crowd ladened photo with the crowds packed tight around him, and also within a shot made once a path had been cleared to the car-- no view is offered into the vehicle. I believe there are at least 2 more photos shot from this vantage point, where Hamer is positioned in the street on Clyde's side of the vehicle or elevated on the driver's side running board-- to perhaps address the crowd or gain order. People's idea that a photo of Bonnie and Captain Hamer exists, I suppose comes from the 1967 movie-- where the scene depicting a captured Frank Hamer was invented for the film. A number of lawsuits were won by surviving members of both the outlaw's and lawman's families-- based on inaccurate depictions of the real life individuals.
