Apologies for the bad lighting which makes it look like I've used two colours on the leaves - that's just a shadow.
I remembered having made an M from this set of kit years ago so when I decided to take up embroidery again, I went to look to see if there were any still available. I found a B on Ebay and decided to try that first. The design was printed on cotton, with needle, hoop, cotton threads and instructions provided. Due to being printed on (and the fact that this is not a fabric designed for cross-stitching), the cross-stitching is not precise.
This is a kit which is embroidered inside the 6" flexi-hoop provided. The "Conservation Alphabet" set of kits were based on original paintings by Sheila Mannes-Abbott. I've seen a puzzle made of the entire alphabet. Here's an image of it from the Broward County Library Digital Archives.
