Early Frankford Arsenal pictures needed

Hello IAA,

I am a picture researcher, and I am being asked to look for photos of the ammunition bunkers at Frankford Arsenal. I have inquired with some historical archives who might have some, but if anyone has historical photos of people working in/near the bunkers at Frankford Arsenal (early 19th century through the Civil War preferred), I’d be interested in seeing what you have.

My deadline approaches quickly, fyi.

Please forward your correspondence to:

Thank you in advance for your courtesy,

Martha Witte, picture researcher
