I hate pimping out a photo I have on the BST in the T206 section, but here’s my only Horner.
Mine has a number on it, similar to other examples shared in this thread. Is this also some sort of cut-out of a composite or was this used in producing some other piece? Genuinely curious.
This image was used a few times, including his 1906 Fan Craze and his T206 portrait. Horner was a magnificent photographer!!
