Hi I have noticed some of the variants for This series are incorrectly lettered. This going by the variant descripitions in the back of the issue.
1J Clara Tessier colour Virgin should be 1F
Current 1F Clara Tessier B&W incentive should be 1I
1K 50 Copy Casas Line Art incentive should be 1J
2G Usanekorin Virgin should be 2F.
2H Casas 30 copy Incentive should be 2G
2J Richard pace Virgin Incentive should be 2E
Thanks
