Would be a service to the hobby to make that info easily and permanently available.
== > And yes, would agree with your definition of the R89 MM 'master set': 96 'Type 2' cards plus #1-24 in the 'Type 1' (answers on back) version. Actually, I am curious as to how many Type 1 subsets are being held by our Forum members? (I'll open the voting with my own 'yes' answer to that question . . .)
