Those are really nice, I don't see that pony insulator too much up here. What's your Mountie can? Drewry's? They're the only company I can think of that used a picture of a Mountie but didn't know they had a can.
Bear / Robert, Both are nice, collectible insulators with values in the $3 - $5 range. I agree with CanadianBottles that that particular pony is not often seen. I think it is underrated in the Price Guide. If the color is determined to be Blue Aqua the listed value is $5 - $10, Blue $10 - $15. Fine lines and the beholders perception separate them.
