In this image, yes it is. However, Take two quarters and put one 8 feet away and the other 9 feet away and you will have a good representation of how the moon appears to the naked eye at perigee and apogee. Now if these quarters are against a plain background, and far enough apart that you can't directly compare them side by side, you would be hard pressed to notice the difference in their apparent size.

Betcha a silver quarter I can see the difference. The lunar angular diameter can vary from 29.43 arc minutes at apogee to 33.5 arc minutes at perigee—over 4 minutes of arc -- or an increase of around 14% in apparent diameter or 30% in apparent area . Of course, that is according to WikiLeaks-a-pedia...and they got it from NASA. They wouldn't lie to us would they? :))
