Canada Sc #J15a/20a (1935) – Fourth Postage Due IMPERF PAIRS VF NH

1c to 10c dark violet Fourth Postage Due issues in imperforate pairs. A lovely set, each with large margins and bright, fresh colour. Full, immaculate original gum, unusual for this issue, with Unitrade noting that "most imperforate pairs have slightly disturbed gum." Very Fine. Never Hinged. A scarce imperforate set.
