Specimen collected at the 700 block of Irving Street NW. Washington DC, June 2007. It appears to have religious significance. The civilization which left this artifact must have had very strict guidelines for worship...
SPECIMEN excavated on the 400 block of Irving Street NW, Washington DC on 30may2007. Size and design consistent with standard "postcards" of the time. 
Recto: Pictograph suggesting the use of meat/food item as a habitable structure or place of commerce, with words "HAPPY HAMBURGER" across the top/roof surface. Ball-point pen marking near the lower center. Evidence of shoe tread by patterns of dirt on card surface, suggesting item had been walked upon.
Verso: Further ball-point pen markings, emulating a standard postcard format, but illegible. Lighter blue coloring inside "stamp" box area (suggesting an attempt to counterfeit postage?). Semi-triangular shape also drawn near the left-center of card space. Item builder identified at bottom left corner, as "Pleasant Company."
