JCM 175: c.1947 Baseball Tournament

THe catalogue/guide only lists the three named cards in this set (Oshita/Wakabayashi/Sugiura), but mentions that there are a number of generic cards. Below is one of the unlisted generic cards:

JDM: Uncatalogued #27 - Airplane #11

This airplane has a blank back.

JDM: Uncatalogued #26 - Airplane #10

Here's another set, with a cross hatching pattern on the back.

JDM: Uncatalogued #25 - Airplane #9

This set is similar to another, but there is less writing on the back of the wings of the planes. Here are some I found online in an auction listing:

JDM: Uncatalogued #24 - Airplane #8

This one is similar to others, but there's less writing on the backside. This one might also be of the same set, but there's no writing on the backside besides the menko number.

JDM: Uncatalogued #23 - c.1950 Airplane #7

Here's another unique airplane shape.The design is similar to another, but there is a team name on the top of the wings, and a name on the back of the wings.

JDM: Uncatalogued #22 - Airplane #6

This looks similar to another type, but there's a number on the top of the airplane.

JDM: Uncatalogued #21 c. 1948 Airplane #5

This one is similar to others, but there is more writing on the backside, and the diecut shape is different.

JDM: Uncatalogued #18 - c. 1949 Airplane #2

Here's another uncatalogued diecut airplane set that I saw in an auction.

JDM: Uncatalogued #17 - Diecut Airplane

Here's a diecut airplane that hasn't been catalogued yet, though it was shared online.

JCM: Uncatalogued #28

This is a set I saw in an auction online - while the fronts are generic cartoons, they do list specific player names. The backs have a large baseball with a team name on front.

JCM: Uncatalogued #27 - Trophy Back #5

Here's another version of an uncatalogued card with a trophy back. This one was seen in an auction that described it as being a Keiu U player.

JCM: Uncatalogued #26 - c1926

This set seems to feature a Keio vs. Wadeda U game, possibly from 1925, and a Championship ceremony for Shinko high schol. Here's what I believe is a complete set, pulled from images of an uncut sheet that sold in an auction online.

JCM: Uncatalogued #24 - Baseball Play Back

Here's a unique group of cards I found online, featuring a back with a baseball play going on.

JCM: Uncatalogued #22 - Trophy Back #3

Another generic set, featuring a trophy back, this time with a large ball and bat. Here are a few uncatalogued ones I've found on ebay.

JCM: Uncatalogued #21 - Trophy Back #2

Another early and generic set, this time having two gloves next to the trophy. Here are some uncatalogued ones I found on ebay:

JCM: Uncatalogued #20 - Trophy Back #1

Here are some uncatalogued cards I found on ebay. They feature a trophy on the back, and a Big6 University player position on the front.

JCM: Uncatalogued #19

Here's a set that I'm trying to get more info on. At first, I thought it was earlier, until I found a cartoon-style front that made me think it fit more into the 1960s-1970s. The diagonal split back reminds me of JCM 15a, which was a 1972 release.

JCM 131c: c.1957 B&W Six Digit Animal

Below is some uncatalogued cards I found for sale on ebay from this set:
