The picture Bohrmann hands to Klink has no white border on it. The one shown in Klink's hands has a white border.
At the end of the episode when Newkirk bluffs his way into winning a hand of poker, Kinch exclaims that he had "one-eyed kings." However, in a standard deck all kings have two eyes, this appears to be a miscue on the popular "one-eyed jacks" in most decks of cards.
Correction: This is not entirely true. In a standard deck of cards, the King of Diamonds has only one eye. The king is also depicted with an ax behind his head and so is sometimes referred to as a "suicide king".

The outside shot of the Hauserhof Hotel has a sign above the entrance indicating it is the Grindelwald Palace.
When Hogan and Newkirk check in the first night, Hogan, Newkirk, and the hotel clerk get on the elevator. The clerk closes the elevator door, and a shadow rises up the door, implying the elevator is going up. However, the light reflecting off the clerk's hands is still visible through the frosted glass of the door - but they are not rising, indicating the elevator is not rising, which means the elevator is a prop.
The photographic negative being used to blackmail Klink actually has no image on it - it is completely dark.
Right after the intro, when Klink gets into his staff car, the driver is shown holding the door open, then closing it from the driver's seat. Military protocol would probably not allow that - the driver should have stood and held the door open (as a sign of respect), then closed it before getting into the driver's seat and driving away.
Based on Hogan's position, and the purpose of his unit, there is no way that he would not have known when the paymaster had visited the camp. The survival of his entire group is based on knowing every detail of every event occurring in the camp - including every visit by the paymaster (which should be on a regular schedule anyway). It is possible that Hogan and his men could be feigning ignorance of the paymaster's visit, lest Schultz get suspicious of them, but LeBeau's question to Schultz ("Are you sure?") is genuine - they did not know that the paymaster had been there.
