I think John had great album covers for the most part (at least for his pop studio albums)
BEST TO WORST, in my opinion:
1. Rock 'n' Roll - love everything about it. the old photo, the passers-by, the colored neon lights on the B&W shot
2. Shaved Fish - i love the representation of the different songs on a compilation. too bad his other compilations couldn't have been this clever.
3. John Lennon/Plastic Ono Band - such a peaceful shot. makes me want to be by that tree.
4. Imagine - a very clever concept, but its design has almost taken on a whole new meaning. i bet most casual music listeners would guess that album cover was designed after his death.
5. Imagine: John Lennon [soundtrack] - it's very John.
6. Walls and Bridges [reissue] - you can't help but laugh when you see all them glasses
7. Some Time in New York City - I think that's a great concept...brilliant.
8. Double Fantasy - nothing over the top, but i think it's cute.
9. Wedding Album - ok, so it's plain, but it is very clever.
10. Live in New York City - the typography is what makes it.
11. Acoustic - the only thing that isn't working for the design is actually John Lennon's name at the top.
12. Mind Games - it's a neat concept and a good design, but it does look a bit cut-and-paste close-up
13. Menlove Ave. - pretty cool...nice use of colour
14. The John Lennon Collection - I know the picture should be valued as being taken on the day he died, but it is kind of a frightening stare
15. The U.S. Vs. John Lennon [soundtrack] - That's cool
16. Lennon Legend: The Very Best of John Lennon [B&W version] - good layout, nice pic
17. Wonsaponatime - it's fun, but John's drawing is kinda crude (but I think that works for this album)
18. Walls and Bridges [original] - fun...give him more points for originality
19. Milk and Honey - We've already seen this pose...the colour is nice, and I suppose it's a fitting design for the follow-up
20. Lennon Legend: The Very Best of John Lennon [colour version] - looks better in B&W
21. The John Lennon Anthology - looks kinda juvenile
22. Unfinished Music 1: Two Virgins [nude version] - I'll give 'em points for being original.
23. Live Peace in Toronto 1969 - a bit too bland. unless that cloud is shaped like something i haven't noticed before
24. Lennon [box set] - is that it?
25. Unfinished Music 2: Life with the Lions - looks like a snapshot someone wouldn't even put on Facebook
26. Peace, Love & Truth - ee. looks like a wedding invitation.
27. Unfinished Music 1: Two Virgins [censored version] - honestly, the brown flap makes it look worse. there are other ways they could have censored this without making it look like extra scraps from a scrapbooking session
28. Working Class Hero: The Definitive Lennon - yep. I can't stand it. First off, we've already seen the EXACT same image on Menlove Ave (which is different than alternate shots from the same session). But what really irritates me is the cutoff of the silhouette of his chest. There are ways you could fix this. You could get rid of the shoulder, but then he just looks like a floating head. You could bring down John's image to the bottom of the cover and move "The Definitive Lennon" (increase the kerning, decrease the size) under "Working Class Hero" (decrease the kerning, increase size). I dunno, there's a lot of ways this could be re-designed.
