Before the DTV changeover, you would sometimes see this on analog channel 2. Later TV set makers went from an IF of 22MHz to 45MHz, which would not have worked on a channel 1. And the old 45MHz band ended up with police and fire comms.

Some stations that stayed and/or used native RF channels 2-6 for DTV can be decoded during Sporadic E's (short-skip). Received/DX'd several Low-VHF DTV stations in this manner, including WBRA, KOTA, WPVI, KDLO, WRGB (and pre-"transition" WKYC-DT 2 before they moved to RF 17 post-transition).
But to bring the subject back on topic, nice photos of that TV.
