Maybe this is an easy question for someone with a FDC catalog, but I've searched the internet and haven't come up with any detail on the cachets on these two items.
The first one is Presidential Series Booklet Pane Combo on #10 envelope with a version of the Great Seal of U.S. cachet. It has no identification that I can see, except that in the center of the star is the logo for the United States Post Office Department. Did the post office issue a cachet for the Presidential Series? Or is it one of the generic ones of the day?

This second item does have a name "(c) 1935 C.S. Anderson". (C. Stephen Anderson, I assume). It seems generic to me and a little futuristic for 1935. Unlike today when a special cachet is produced for every stamp, I gather that it was commonplace in the 1930's for generic cachets to be printed and used by collectors on multiple issues.

Any comments would be welcome.
