2 Minnehaha Laughing Water Jugs

Rummage sale find in SFL. 2 Glazed Pottery Jugs in good vintage condition.

First one is marked MINNEHAHA (Laughing Water) with blue picture of Indian Maiden and marked Martindale & Johnston  Philadelphia across the bottom.  There is a monogramed emblem on back. Its in good shape with the only damage I see is a crack that runs about 1.5 inch around neck of jug. No apparent crazing and just a few little dinks.

Second jug is marked the same as above with a blue picture of Indian Brave slaying a dragon.  There is a fair amount of crazing of the finish on top of this jug and there is a 1/4 inch chip out of handle.

I've done a little research and realize these might be valuable and would appreciate any expert advice you can give me on the value.  Thank you
