The First Trip North

It's been relatively quiet - so time for another in the memorabilia series. This is a My Aim Is True promo poster put out by Columbia Records in Canada to promote EC's first record. It's a standard sized 2x3 (approx. poster).
I have it marked as 1978 so the Canadian release may have trailed the US release by a few months. Anyone with more info, please leave a comment.
