  We present short proofs of two Tverberg-type theorems for cell complexes by
S. Hasui, D. Kishimoto, M. Takeda, and M. Tsutaya. One of them states that for
any prime power $r$, any simplicial sphere $X$ of dimension $(d+1)(r-1)-1$, and
any continuous map $f:X\to\mathbb R^d$ there are pairwise disjoint faces
$\sigma_1,\ldots,\sigma_r$ of $X$ such that $f(\sigma_1)\cap\ldots
f(\sigma_r)\ne\emptyset$.
