Just noticed the scratches in this example of scott 143. I don't have a copy of the scott catalogue that covers colonial Senegal. Does Scott or anyone else for that matter mention this error? I've found a couple other examples online. Thanks
Phillystamper, if you have access to those other images you found and they are not with copyright, could you add them via edit to your original post? At least one would confirm the scratch as a scratch for later readers of this thread.
Now-a-days, sometimes is it posts such as yours that brings information to the masses when such is not deemed for catalog inclusion.
Now if you have any desire to see your name in print, you could send a short article with illustration to EFO Collectors' Club's journal, The EFO Collecter's editor. Afraid of your writing skills? That is what editors are there for, edit, review, assist and suggest.
