  New York Bottling Co, 729 11th St SE (1906-1907)

Notes:
Isaac Robin (1873-1952)³ was a grocer in Washington DC. In the 1905 & 1906 Washington DC city directories, he was listed as being teamed up with Benjamin Katz, with a grocery store under the name "Robin & Katz". Then in the 1907 city directory, both Robin and Katz are listed as owners of the New York Bottling Company. 1907 is the only year that said bottling company was listed - in the subsequent years, Robin was again listed as a grocer, without Katz. ¹

The bottles below have a monogram logo that either says "RK" or "RKF" (although the letters are not necesarily in that order). I'm pretty confident that the "RK" refers to Robin and Katz. But I don't know who the "F" refers to in the "RKF" monogram. My guess is that Robin & Katz had a 3rd partner whose last name started with the letter "F" at some point in their short-lived bottling business.

	book # 435 These are similar to the bottle above, except they have a monogram "RK" vs. "RKF". They are 8" mouth-blown crown top bottles. The left one is aqua, and the right one is clear. They are both embossed: round slug plate: NEW YORK BOTTLING CO / ('RK' monogram) / REGISTERED / WASHINGTON, D.C. below slug plate: THIS BOTTLE NOT TO BE SOLD back on heel: H5 base: 'RK' monogram
	book # 435 This bottle has a slightly different slugplate from the one above, with the way "WASHINGTON DC" is arched, and the location of the word "REGISTERED". It's an 8" aqua crown top bottle embossed: round slug plate: NEW YORK BOTTLING CO. / KR / WASHINGTON D.C. below slug plate: REGISTERED base: KR
	book # 435 This is a 9.4" aqua crown top bottle embossed: shoulder: REGISTERED round slug plate: NEW YORK BOTTLING CO / ('RKF' monogram) / REGISTERED / WASHINGTON, D.C.
	book # 435 This is an 11.4" aqua crown top bottle embossed: round slug plate: NEW YORK BOTTLING CO / ('RKF' monogram) / REGISTERED / WASHINGTON, D.C. It appears to be BIM (not machine made), which is unusual for a picnic sized bottle.
