Large collection of Congo pre-1940 issues

Description

This is one of what will eventually be 81 lots created as I break up a U.S./WW album.  I don't have the time, energy, or the expertise to describe non-Scandinavian lots in detail, so for the most part these will be what-you-see-is-what-you-get offerings.  I'll offer brief notes about each lot in an italicized, indented paragraph.  The boilerplate below that will apply to all the lots.  All of the stamps will be shown in the scans, often with an introductory composite image, and sometimes with closeups of groups of the same stamps.
This lot consists of a collection of the stamps of Congo pre-1940, including regular issues, semipostals, airmails, and postage dues.  This lot will need to ship intact in a large 9x13 envelope, and thus will go to domestic addresses only.
My new listings this week include Cochin China, Colombia, and Congo (all pre-1940)
, plus a stockpage of Denmark early issues, a couple album pages of Denmark pre-1940, and Denmark issues #65-69, #81 (35o on 32o) MNH, #136 (80o on 12o), and #137 postally used.
General comments
:  all of these lots are from a collection created by someone else, so I can't guarantee that the stamps are correctly mounted with regard to perfs, watermarks etc - but all of the ones I have removed and checked have been correctly placed, and I assume that is generally the case.
All of the mint stamps are mint hinged
, and all of the hinges are of the modern glassine type, not folded selvage (most of them are easily peelable, and some so dry that the stamps have fallen off the page and needed to be remounted).  To minimize your shipping costs I have transferred stamps from sparsely-filled pages to stock pages (and stamps scanned on sparsely-filled pages may be transferred to cards or glassines for shipping).  The collection is exceptionally clean and tidy, with very few even minor faults (which I will try to note if on valuable stamps), and there are a pleasing number of mint early issues (Victorian era etc).  I am not checking these stamps for back faults, but the lot is returnable if you encounter a problem with them.
For
shipping
, stamps on stock pages will travel in glassines or cards.  When possible I will fold album pages so they will fit into standard 6x9 mailing envelopes; since some pages are double-sided, this may sometimes necessitate removing one row of stamps from the front or back by slitting (not peeling) the hinge, and moving them to a glassine.  The album pages have already been trimmed to fit into page protectors, and for shipping I may trim them further to minimize shipping weight and your cost.  When there are multiple album pages, they will ship in a large 9x13 mailing envelope, which is unfortunately outrageously expensive for non-domestic destinations.  I will happily combine small lots for discounted shipping, but larger size ones may need to ship individually to avoid overloading the envelopes.
