And that includes almost all cartoons animated in the years 1944-1952.
Jerry and Jumbo was animated in 1951, but released in 1953.
These cartoons had the best look/animation, still Tom & Jerry developed in that era few times: I would say 1944/45, next 1946/47, then the "classic" look 1947-1950, and 1951/52.
Gags were great, not too cute like in later years and not too slow just like in the early years. The cartoons from first 3 years were with more than 8 minutes a little bit too long and not that fresh and naughty like the cartoons from 1944-52 with the great ideas.
Ps.: Rhapsody Rabbit was made the same year The Cat Concerto was made (1946): From Wikipedia "Both MGM and Warner Bros. accused each other of plagiarism, after both films were shown in the 1947 Academy Awards Ceremony. Technicolor was accused of sending a print of either cartoon to a competing studio, who then plagiarized their rival's work. This remains uncertain even today: though Rhapsody Rabbit has an earlier MPAA approval number and release date, MGM's cartoons took longer to make." That one goes to an early review by another user.
