Earlier this year I found and quickly sold a bunch of rppcs from the same batch as these two--I just went back to the source and dug out this pair I missed the first time around. As a group, the images documented the growth of beans, corn, peas and oats in various soils and combinations, and I just love them--as beautiful photographs, for their indexical nature, for the wonderful hand-written labels on the planters, and for being, as far as I know, quite unusual. The fact that they were produced as postcards suggests they were made to be sent, but the backs are all blank, so perhaps they just served as reference for the grower, who I like to picture carrying them all in to Modern Photo Studio in downtown Boston, c.1910s-20s, and setting them proudly before H.A. Kazanjian to photograph.

These two document oats growing in pulverized rock and water, and peas growing in limestone and water.  3 1/2" x 5 1/2" and in very good condition. Sold as a pair; price is for the pair.
