Yeah! But now that I’m looking at it more closely, the text on the top right makes me think maybe it’s Canadian. And I remember when I was a kid, noticing the Canadian prices on the backs of my books were a bit less than 1.5 times the USD prices (because i am nerd). So perhaps with the exchange rate at that time, it wasn’t so much?
