Different subset. Looks to be uncataloged by Keetz (I have the 2nd edition of his book)
Kind of like the H804-1 Tobin "Baby Talk Series" has 4 subsets,...... H804-1A, H804-1B, H804-1C, H804-1D.
H804-2 has 3 subsets, H804-5 has 3 subsets, H804-7 has 4 subsets, etc.
Now you just have to see if there are more cards in this set
Im sure there are and the captions may be the same as the "known" H804-26 set, like the "Oh What a Snap!" is.
