Lake Michigan (1948), Nautical Chart, scale 500000.
Visual descriptionwritten by a machine · unchecked
A vertically oriented nautical chart shows a long body of water surrounded by detailed coastlines, bays, islands, depth soundings, navigation symbols, and latitude-longitude grid lines. Two compass roses and several red circular navigation diagrams are visible, with a large printed title and explanatory text in the lower-right portion.
A model wrote this. It was shown the image and the catalogue record together, and asked to keep them apart — what it saw is here, what the record told it is under "taken from the record" below. It is still wrong often enough to matter, about who is pictured, where, when, and what is happening. Read it as a way to find the image, never as evidence about it. If you can correct it, please do: write to michael.bommarito@gmail.com, or see how corrections work. Someone who recognises a face or a shoreline knows more than the model did.

Could not make out

Material goes off the web without anyone deciding that it should: a host lapses, a gallery is retired, a link stops resolving. Holding a copy — with its provenance, its checksum and its holder's terms recorded beside it — is much of why this archive exists. If you are looking for something whose original has since gone, write to michael.bommarito@gmail.com and a full-size copy of what is held here will be sent to you.
Recorded verbatim from the provenance sidecar taken at retrieval — this archive does not restate a holder's terms in its own words, does not add a restriction the holder did not state, and does not abridge one.

The archive holds its own copy of that file and will supply it on request; it is not re-served here, because the holder serves it better and a second copy is a second thing to go stale.
