Should I obtain permission for publishing a vector drawing based on a published photo? I have drawn a schematic image of a museum object for use in my forthcoming paper. The object itself is over 1000 years old, and my vector drawing is based on a photograph published in an exhibition catalogue some 30 years ago (where the photograph is credited to the museum holding the piece). I will of course give credits to the image source in the caption ("Drawn by the author based on the photograph published in Smith 1985, 88 fig. 88" or "Drawn by the author based on the photograph published in ABC 1985, 88 fig. 88 (@ Museum XYZ)"). However, I would like to ask if I should also obtain a permission for publishing my drawing, as I would do if I republish the photograph itself. Or does the fact that I have drawn the image myself free me from that obligation? 

My question is thematically close to the two earlier topics on Academia SE ( How do I give credit to some image I included in my paper? and Recreating images from a source ), however these earlier questions concerned primarily with credits, and my question with getting a permission. Besides in these earlier questions the image sources were drawing, and mine concerns with a photograph as an image source.
What is your original motivation to create that drawing? Escape reproduction rights? Or else? 

The usual practice with museums and objects that are not involved in copyright any more because they are too old, is that you don't pay for the picture of the image if you take the picture of the image yourself. You pay if you use the image that the institution provides.

My guess is that publishing your drawing is not like 'republishing the photograph itself' because your drawing makes an original contribution that goes far beyond reproducing like for like the original photograph.

Agreed with commentators about approaching the institution out of common courtesy, if nothing else.
