Sorry that these pics are blurry, but it was dark in the antique shop!  This is an electric Weenie Cooker.  It has spikes inside, where you spork your weenie, and it is supposed to heat them up.  I think maybe they also rotate, but I’m not sure.  I don’t know if you can tell, but it’s not a printed plaid, it’s a cut-out metal grid that makes up the lid.
