A fun one, with great graphics, and certainly there are some roaches around one might like to be rid of! From what I can tell, Roach DOOM was produced by Edgar Murray Co. of Detroit, Michigan, established 1895; I imagine this copper print block dates to sometime not too long after.
3 3/4" x 2" x 7/8". Excellent antique condition and completely usable should one wish to ink it up, but also just a good object.
