Vintage cast iron bulldog piggy bank

This is a vintage cast iron piggy bank with 3 bulldogs in a blue bag. As a bulldog owner myself, I’ve gathered many pieces over the years and this one is special. I found its image on google and attached the description of it here in the last pic. One description said it was from the 1930’s but I cannot comfirm that! Although this one is from an estate sale decades ago. 🩷
