Vintage 30s? Hand Worked Small Embroidered Doily Garden Butterfly Upcycle 22cm x 23cm

Item: very vintage smaller hand worked doiley in a bone linen and an embroidered garden scene with hovering butterfly.
Era: I am leaning towards the 30s, but at the very least it's 50s.
Size: 22cm x 23cm
Condition: This piece is very old and has age spots and marks - I feel with a loving soak everything will wash out and it will come up beautifully - please see photos. The last photo shows a ruler and the back of the doily.

I am now uploading general antique or vintage textiles for people to use as-is or to upcycle into something sublime. I was building packs around these old pieces but I thought people would like to choose their own pieces and build their own packs to enjoy.

The doilies I upload will vary in condition and will suit a range of uses - either perfect to use as-is or damaged/aged. I will do my best to note anything glaring above.

I am not a doily expert and encourage you to view the photos of the item. I know collectors can age doilies within a split-second, so I encourage those of you who collect these pieces to view the photos to see the condition and embroidery detail.
