Yep, SAME mouse, but TWO DIFFERENT CLOCKS!
As I wrote at Grand Comics Database for the "Little Roquefort Feature Object" entry:
"Beginning in 1950, Little Roquefort was Terrytoons’ “other starring mouse character (of the non-mighty variety)", during the theatrical amination era. Paired with the requisite “cat-co-star”, Percy Puss, they were Terry’s answer to MGM's Tom and Jerry."
So, lessee... what do mice generally do? Um, they eat cheese! They flee from and/or torment cats! And... and.. and... THEY RUN UP CLOCKS! Yeah, that's it!
While most mice usually run up ONE clock (...or maybe run up and down the same one over and over again), Little Roquefort runs up TWO DIFFERENT CLOCKS (and for two different publishers, yet) for today's Mirth Separation!
Here's "An Olde Rhyme", from DINKY DUCK # 4 (St. John Comics, Cover Date: May, 1952), followed by "Nursery Rhymes", from MIGHTY MOUSE # 70 (Pines Comics, Cover Date: September, 1956).
Pines was the successor-publisher for the Terrytoons properties, following St. John - and I must say that, looking at this 1955-1956 transition, it feels not unlike the transition of the Hanna-Barbera properties from Gold Key to Charlton in 1970 - with Pines in the role of Charlton!
...But that's another topic for another day... Here's Little Roquefort "Separating Himself at Mirth" first at St. John and then at Pines! Click to Enlarge!
In this case, the Pines version may actually be the better gag (even if the rhyme is totally and awkwardly abandoned)... but, ooohh, that LETTERING is so hard on the eyes!
