Hi, I found this little gem that might be rare. It is a square planter, with a brown drip glaze on a burst yellow/orange. I can not find much about it, nor very many examples, but I did find the only other example of the marking here:

(scroll down to MAYTIME to see the bottom mark posted there. Like the item I have, but with different mold numbers...)
I have never heard of this before. I do not have a date they were made, where in Canada, or the era dates of company, etc...
