I am not as familiar with these years as I am with pre 1980 material. This would be really worth getting other opinions on. Be sure to examine this unframed - that can hide a lot or be done incorrectly.
Interest is greater, of course, in Bowie signed Bowie LP's. I have seen signed authenticated Bowie LP's sell for less, and I have seen certified Tin Machine 8x10's (with better contrast) go for more. If genuine, this has the added benefit of being multi-signed.
