This is the 10th bust in the "Women of the DC Universe" series.  Big Barda is the biggest bust in the series, maybe that's why they call her "big".  hmmm.  It's a great pose, dressed in a bikini holding Mister Miracle's cape.  Since she's a secondary character DC decided to drastically cut production numbers to 3500.

Note about shipping
Statues have some of the greatest variances in shipping prices.  I've seen shipping costs from $2.50 up to $20.00. 

To buy or not to buy
DC priced this one about right when they released it at $45.00.  Less known character so lower production, those 2 factors balance it out.  Don't expect a big jump or drop in price unless DC features her in some upcoming storyline.
