Wells Fargo Express Franks on Numeral Envelopes, extraordinary collection in four albums, approximately 183 mint and 372 used envelopes, spanning all of the Numeral issues (MEPSI WF 22/83) and including very nearly all major catalogue listings, light to moderate duplication throughout, a huge wealth of different origination handstamps, note foreign destinations (mostly Germany and the US), a few certified covers, minor varieties including some which do not appear to be listed in the UPSS catalogue, some mixed condition to be expected given the huge volume of covers but the majority fine to very fine or better, an ideal lot for the specialist in either express companies or Mexico postal history as this could very easily translate into the foundation for a strong exhibit, similarly would make for a wonderful stock for the postal history dealer, in any case a collection such as this is most likely impossible to duplicate and is not to be missed (approximate UPSS value $15,000+)
