Frank's work has been succinctly summarised (here) thus...
From here on ComicArtFans - thanks
As well as Riders of the Range Frank would also go on to illustrate the Blackbow the Cheyenne strip in Eagle in the 1960s
Most of the images I've never seen before, some certainly pre-date his time on Eagle - I'll highlight them on the blog today and tomorrow.
No idea where this was from - a spot illustration in a magazine like Lilliput maybe??
A much simpler illustration style than we're used to seeing from Humphris
this image (above) has now been identified (below)...
...as being from this book...
A negative of Humphris magisterial illustration of Custer's last stand
Unclear if Humphris illustrated the book cover or just liked the book
From 1942 - the earliest piece of Humphris art I've ever seen
Probably a partner to the 2nd image (above)
Come back for more tomorrow!
