Stadium Seat - Milwaukee County Stadium

So, I stopped by what ended up being a relatively disappointing card show late last month right before Opening Day.

But the one saving grace was this Eddie Matthews stadium seat card from old Milwaukee County Stadium.  I already have three other stadium seat relic cards, as well as an outfield wall relic card, so I jumped at the opportunity to grab another for a reasonable price.

I am interested in what other people think about these sorts of relic cards: more or less interesting than bat or jersey cards?
