The International Printing Museum posted a couple of cards from this series and made me search further to find the series. The University of Wisconsin-Madison has an online display of almost all 24, but are missing #8. Here’s what they have.
Update: I found #8. It is the Case Layout card for a California Job Case. It was probably missing because it’s still tacked to the wall wherever the rest of the collection came from. Anyway, I put them all together in one PDF here.
