I remember when I was a little kid in the late 80s early 90s around the holidays and an old cartoon came on. The cartoon was probably from the 30s or 40s, (but might have been a 50s or 60s) about a TOY SHOP OWNER locking up the place at night and the toys all coming to life. I believe the beginning, featuring the old Shop Owner was in song or poem-narration.
Probably not this as Terrytoons aren’t shown much and it’s in.black and white.
Here is the same cartoon with a live action intro that was added in 1945. Santa introduces the cartoon with a rhyme.

By the way, it was pretty common in the 193o’s for cartoon with toys that came to life.
Mr magoriums wonder imporium? It’s fairly recent the one I’ve seen but it’s the same sort of story line. It could be a remake?
