Found on Ebay here.
I had forgotten about this toy for about forty years. When I started searching for "plastic steam roller," I wasn't sure I'd even remember what it looked like...and I think my grandpa might have had more than one.
But this was one of them. Almost for sure, unless my mind is completely playing tricks and I'm thinking of my aunt's grey-and-red roller skates.
My grandpa? He loved steam trains and steam farm equipment. He drove a vintage steam tractor at an annual Labour Day steam fair. Somebody probably gave him this for a joke present...and it became something for the grandchildren to play with. Being the oldest grandchild, that would have been me, until the others came along. On the floor, from the dining room into Grandma's kitchen, and back again. Over the heating grate. Back to the kitchen again.
I'd forgotten. Sometimes it takes a picture to drag things up.
