G1 picture frame details???

[Gingerbread]

Does anyone have one of these? I'm trying to figure out about what size picture it holds for a possible future project.

Based on the size of the price tag, I would imagine it’s for a smaller photo.

Will it appears to me that it the same size as a back card of a my little pony but i can't tell in the photo i don't own one but i do like the look of it

I don't have one of these, but I think 3 x 5 was the most common size then. So that's my guess.
