I want to buy a t-shirt with Sputnik 1 on it.  The satellite.  I guess
there's a band out there called Sig Sig Sputnik or something; don't
want that.
I don't want any custom "make your own t-shirt" deals, because with
those you either have to buy in bulk, or it's just a crappy
photo-transfer.
Would like a medium one.
Don't really have any specifications beyond that.  Pretty much any
color is fine.  I live in California, USA, so a store or merchant that
won't ship there is no good.  Thanks!

Hello.

I have located a T-Shirt with Sputnik 1 on it.  The shirt is made by
L5 Development. It was issued to commemorate the 45th anniversary of
Sputnik. It's available in black or white. Medium is available.
