CARS: 1958 Ford Thunderbird convertible, black, top down (Drake), 1958 Ford Skyliner retractable, black, top up (Mason), Cameo: 1958 Edsel 4dr hardtop. From The Cars by Greg Cockerill.

As she did in episode 40 and 41, Della wears her pendant with the initials D.S. in script. Submitted by PaulDrake 33.

In the opening scene, Hans Breel drives a sports car up in front of an apartment building. When he applies the brakes, the front tag of his car has been attached so poorly that it almost comes off. The front tag, DHR 786 is the same tag that is on Carl Reynolds’ Pontiac in episode 44, TCOT Curious Bride. Submitted by PaulDrake 33.
+ Here's the scene at about 59 seconds, just before Breel comes to a stop; at 01:23, Breel enters the building. You will see the loose plate shake just after 00:59. Here's a later shot (13:32) of Breel's très élégant 1958 Simca Aronde Océane with promiscuous plate# DHR 786. That's the 1958 Edsel Citation 4-Door HardTop (from "CARS", above) beyond Breel's Simca. Looking through the Edsel's interior, it's Paul's black 1958 Thunderbird Convertible, white top up, with Sarah Werner and Paul inside, staking-out the location.
++ Here's a color photo of a '58 Aronde Océane. Those are SIMCA hubcaps, not Studebakers! Aronde Sports cars (60HP/90mph) were roughly equivalent in price & performance to the contemporary Triumph TR3, MGA and Alfa Romeo Giulietta. See Comments section for more on Breel's car, Simca and the Aronde line. Simcas appear again in Episodes 107 & 190. Added by Gary Woloski, 3/8/14.
+++ That license plate DHR 786 first appeared on Harriet Bain's car in episode 21 TCOT Green-Eyed Sister. Added by H. Mason 10/15/14

Location: About 4:45 into the episode there is a quick shot of the classic clothing store Mullen Bluett at 5570 Wilshire near Ridgeley. Preservationists tried to save this building just east of the La Brea Tar Pits, but sadly it was demolished about 2004. Submitted by Eric Cooper, 9 December 2010.
+ That was a good-looking building. Submitted by DyNama, 9/1/2014
++ Although peripheral - at best! - to the episode, MB serves as a microcosm of life in Southern California in the 20th Century. Founded in the 1880's, by the 1920's it occupied a large store on Broadway. It then constructed a number of branches - a Tudor style in Hollywood and Churrigueresque in Pasadena (an eclectic mix, as is common in LA); the branches didn't survive the Depression - and sadly neither of the buildings has survived either - and when the firm expanded again after WWII, it was in modern buildings in decentralized settings.

Sightings: Sitting behind Perry Mason at the hearing is Little Old Lady #2, and two rows behind her, Quiet Old Man #1. We find “Miss Carmody” in the gallery, too. After lunch, Little Old Lady #1 shows up (in a cutaway to Morrow and Schoenbeck), and so does Distinguished Gentleman #1. Submitted by g, 30 January 2011.

An unusual example of correct grammar is heard when Lawrence David identifies the defendant by saying "That's she." Most writers would have written (and most people would have said) "That's her." Submitted by Wiseguy70005, 10/13/13.

+ Maybe Diamond dealer David's mother was an English teacher. My parents were teachers, and when I was a child, much of our dinner table entertainment involved correcting other people's grammar. JohnK, 24 August 2022

Incorrect Show Summary: Della actually said the perfume cost $150 a half ounce. Submitted by Duffy, 5-15-2014.

Set Decoration Goof: When Beers first sits down at his bench, there is a diagram of the Pundit's Dream "Right Side" on the wall -- and the rest of the wall is blank. But ... the diamond has not yet been purchased by Hands and is not yet in the Trent workrshop! Later, when the first cleavage is to take place, the various views of the diamond -- Right, Left, Top, Bottom, and so forth -- are all on the wall and are discussed by Breel, Beers, Davis et al. That first "Right View" hanging on the wall was a rather big error, in my opinion. Submitted by catyron, December 24, 2020
